FEATURES●Ultra Low Noise Output●High Output Voltage Accuracy●Guaranteed 150mA Output●Maximum Output Voltage of Adjustable type is 8.5V.●Low Quiescent Current●Low Dropout Voltage●Extremely Tight Load and Line Regulation●Very Low Temperature Coefficient●Current and Thermal Limiting●Reverse-battery Protection●“Zero” off-mode Current●Logic-controlled Enable●Moisture Sensitivity Level 3APPLICATION●Cellular Telephones●Laptop, Notebook, and Palmtop Computers●Battery-powered Equipment●PCMCIA V CC and V PP Regulation/Switching●Consumer/Personal Electronics●SMPS Post-regulator/DC to DC Modules●High-efficiency Linear Power Supplies3.8,4.0,5.0DESCRIPSIONThe TJ5205 is an efficient linear voltage regulator with ultra low-noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (600µA at 100mA output).The TJ5205 offers better than 1% initial accuracy. Designed especially for hand-held, battery-powered devices, the TJ5205 includes a CMOS or TTL compatible enable/shutdown control input. When shutdown, power consumption drops nearly to zero.Regulator ground current increases only slightly in dropout, further prolonging battery life.Key TJ5205 features include a reference bypass pin to improve its already excellent low-noise performance, reversed-battery protection, current limiting, and over temperature shutdown.The TJ5205 is available in fixed and adjustable output voltage versions in SOT-23-5 PKG and SOP-8PP PKG. And adjustable type’s maximum output voltage is 8.5V.Absolute Maximum Ratings (Note 1)(Note 2)Ordering InformationOrdering Information (Continued)Package Type Root Name Product CodeOutput Voltage : ADJ / 2.5V / 2.7V / 2.8V / 2.85V / 2.9V / 3.0V / 3.3V / 3.6V / 3.8V / 4.0V / 5.0V SF5 : SOT-23-5L DP : SOP-8PP D : SOP-8PIN CONFIGURATIONVOUT N.C N.C BYP/ADJVIN GND N.C ENSOT-23 5L SOP-8 / SOP-8PPBLOCK DIAGRAM[ Ultra-Low-Noise Fixed LDO Regulator ][ Ultra-Low-Noise Adjustable LDO Regulator ]TYPICAL APPLICATION- Typical Fixed Output ApplicationV OUTV INEN- Typical Adjustable Output ApplicationV INV OUT EN* Note) BYP pin can be left open if low noise operation is not required.V OUT = V REF(1+R2/R1)V REF = 1.242VV OUT(min) = 2.0VELECTRICAL CHARACTERISTICSV IN=V OUT+1V ; I L=100uA ; C L=1.0uF; V EN≥2.0V ; T J=25°C, bold values indicate -40°C ≤T J≤+125°C; unless noted.Enable InputNote 1. Exceeding the absolute maximum rating may damage the device.Note 2. The device is not guaranteed to function outside its operating rating.Note 3. The maximum allowable power dissipation at any T A (ambient temperature) is P D(max)=(T J(max)–T A)+ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.Note 4. The TJ5205-ADJ has V REF=1.242V±1%, but minimum output voltage for TJ5205-ADJ must be above V OUT min=2.0V.Note 5. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.Note 6. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.Note 7. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential.Note 8. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current.Note 9. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects.

The MIC59150 utilizes two input supplies, significantly reducing dropout voltage, making it perfect for low-voltage, DC-to-DC conversion. The MIC59150 requires a minimum number of external components, and as a μCap regulator, the output is tolerant of virtually any type of capacitor, including ceramic type and tantalum type capacitors.The MIC59150 regulator is fully protected from damage due to fault conditions, offering linear current limiting and thermal shutdown.Bias Supply VoltageV BIAS, requiring relatively light current, provides power to the control portion of the MIC59150. V BIAS requires approximately 12mA for a 1.5A load current. Dropout conditions require higher currents. Most of the biasing current is used to supply the base current to the pass transistor. This allows the pass element to be driven into saturation, reducing the dropout to 100mV at a 1.5A load current. Bypassing on the bias pin is recommended to improve performance of the regulator during line and load transients. Small ceramic capacitors from VBIAS to ground help reduce high frequency noise from being injected into the control circuitry from the bias rail and are good design practice. Good bypass techniques typically include one larger capacitor such as 1μF ceramic and smaller valued capacitors such as 0.01μF or 0.001μF in parallel with that larger capacitor to decouple the bias supply. The VBIAS input voltage must be 2.1V above the output voltage with a minimum VBIAS input voltage of 3V.Input Supply VoltageVIN provides the high current to the collector of the pass transistor. The minimum input voltage is 1.0V, allowing conversion from low voltage supplies.Output CapacitorThe MIC59150 requires a minimum of output capacitance to maintain stability. However, proper capacitor selection is important to ensure desired transient response. The MIC59150 is specifically designed to be stable with virtually any capacitance value and ESR. A 1μF ceramic chip capacitor should satisfy most applications. Output capacitance can be increased without bound. See the “Functional Characteristics” subsection for examples of load transient response.X7R dielectric ceramic capacitors are recommended because of their temperature performance. X7R-type capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much as 50% and 60% respectively over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic or a tantalum capacitor to ensure the same capacitance value over the operating temperature range. Tantalum capacitors have a very stable dielectric (10% over their operating temperature range) and can also be used with this device.Input CapacitorAn input capacitor of 1μF or greater is recommended when the device is more than 4 inches away from the bulk supply capacitance, or when the supply is a battery. Small, surface-mount, ceramic chip capacitors can be used for the bypassing. The capacitor should be placed within 1" of the device for optimal performance. Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage.Thermal DesignLinear regulators are simple to use. The most complicated design parameters to consider are thermal characteristics. Thermal design requires the following application-specific parameters:•Maximum ambient temperature (T A)•Output current (I OUT)•Output voltage (V OUT)•Input voltage (V IN)• Ground current (I GND)First, calculate the power dissipation (P D) of the regulator from these numbers and the device parameters from this datasheet.OUTOUTBIASBIASININDIVIVIVP×−×+×=The input current will be less than the output current at high output currents as the load increases. The bias current is a sum of base drive and ground current. Ground current is constant over load current. Then the heat sink thermal resistance is determined with this formula:()CSJCDAMAXJSA PTTθθθ+−⎟⎟⎠⎞⎜⎜⎝⎛−=)(The heat sink may be significantly reduced in applications where the maximum input voltage is known and large compared with the dropout voltage. Use a series input resistor to drop excessive voltage and distribute the heat between this resistor and the regulator. The low-dropout properties of the MIC59150 allow significant reductions in regulator power dissipation and the associated heat sink without compromisingperformance. When this technique is employed, a capacitor of at least 1μF is needed directly between the input and regulator ground. Refer to “Application Note 9” (/_PDF/App-Notes/an-9.pdf) for further details and examples on thermal design and heat sink specification.Minimum Load CurrentThe MIC59150, unlike most other high current regulators, does not require a minimum load to maintain output voltage regulation.Adjustable Regulator DesignThe MIC59150 adjustable version allows programming the output voltage anywhere between 0.5Vand 3.5V. Two resistors are used. The resistor value between V OUT and the adjust pin should not exceed 10kΩ. Larger values can cause instability. The resistor values are calculated by:⎟⎟⎠⎞⎜⎜⎝⎛−×=15.021OUTVRRwhere V OUT is the desired output voltage.EnableAn active high enable input (EN) allows on-off control of the regulator. Current drain reduces to “zero” when the device is shutdown, with only microamperes of leakage current. The EN input has CMOS compatible thresholds for simple logic interfacing. EN may be directly tied to V BIAS and pulled up to the maximum supply voltage.U1MIC59150YMEJP2=Voltages Selector A VOUT =1.0V B VOUT =1.2V C VOUT =1.5V D VOUT =1.8VJ2GND J3VBIAS 3V to 5.5VJ1VIN1V to 3.8VBill of MaterialsItem Part Number ManufacturerDescriptionQty.

超低功耗、低压差、小封装LDO
上海英联电子科技有限公司杨永华徐宁一、前言
传统的LDO功耗较大，静态工作电流在100uA左右。
对于电池供电的设备，由于大部分时间处于休眠状态，MCU的工作电流仅为几微安，传统LDO的功耗显然不能满足设计要求。
上海英联电子采用低功耗的CMOS工艺，推出了UM1550、UM1560系列，8V静态工作电流仅为2.5uA（V IN=8V），输入电压范围很宽，1.8V～ 8V，输出电流可达250mA。
1.8V的超低输入电压，250mV的低压差（I OUT=200mA）可最大限度的使用电池。
该系列产品可用于电池供电和电源供电两种模式，为客户省去一个LDO，最小封装仅为DFN 1mmX1mm，降低成本、节省空间、延长电池的使用寿命。
二、UM1550、UM1560的重要参数
英联的UM1550、UM1560系列是超低静态工作电流的电压稳压器,可使用1μF以上的陶瓷电容器作为输出电容。
输入电压范围：1.8V～8V，输出电压范围为1.2V～5V。
UM1550系列提供两种封装供客户选择，SOT23-3、SOT89-3、DFN 1X1、DFN 2X2，与市面同类型芯片兼容。
UM1560系列带有使能管脚，封装为SOT23-5、DFN 1X1、DFN 2X2。
其主要参数如表1所示：

I OUT Output C urrent 250 mA
I LIIMT Current Limit R L=1Ω 280 360 500 mA
1、静态电流Iq
静态电流为输出电流与输如电流的差，LDO的效率与输入、输出电压和静态工作电流有关。
效率可由以下公式算出：
效率=Vo×Io
(Io+Iq)×Vin×100%
由公式可看出，当LDO处于轻负载情况下，静态电流就显得尤为重要，Iq值越小，效率越高。
图1为UM1550、UM1560系列LDO在不同输入电压情况下的Iq值。
图1 静态工作电流随输入电压变化图
2、动态负载调整（△VOUT）
当输入电压一定时，输出电压随负载电流的变化而产生的变化量。
只要负载电流变化缓慢，大多数LDO都能轻松地保持输出电压接近恒定不变。
然而，当负载电流快速改变时，输出电压也将随之改变。
当负载电流发生变化时，输出电压的改变量决定负载瞬态性能。
图2为UM1550、UM1560系列LDO的负载瞬态响应图。
图2 负载瞬态响应
3、压差（△V DO）
压差可表示为Vdrop，是指保持电压稳定所需的输入电压与输出电压之间的最小差值。
当输入电压下降到一定程度时，输出电压将不能维持在一恒定值。
其具体算法如下：输入电压为V IN= V OUT(s)＋1.0 V时的输出电压值为V OUT3，缓慢降低输入电压（V IN），当输出电压降至为V OUT3的98%时，此时的输入电压（V IN1）与输出电压的差即为输入输出电压差：V drop = V IN1－（V OUT3×0.98）
压差应尽可能小，以使功耗最小，效率最高。
负载电流和结点温度会影响这个压差。
最大压差值应在整个工作温度范围和负载电流条件下加以规定。
在非调整区域，Vdrop的值呈线性变化，图3为UM1560S-30的压差随输出电流变化的曲线图。
图3 Vdrop曲线图
4、过载电流保护
UM1550、UM1560系列LDO为了保护输出晶体管免受过大的输出电流，以及V OUT管脚—GND 管脚之间短路的影响，内置了过载电流保护电路。
最小限流280mA，负载电流小于限流时，输出电压即可恢复为正常值。
三、应用注意事项：
1、电容的选择：
输出电容及其等效串联电阻ESR，将影响环路稳定性和对负载电流瞬态变化的响应性能。
为了确保输出的稳定性，如果使用1μF输出电容，请尽量选用ESR值为0.3Ω或以下的，推荐X7R或X5R陶瓷电容。
另外，LDO要求使用输入和输出电容来滤除噪声和控制负载瞬态变化，输入电容器因应用电路的不同所需要的容值也不同。
电容值越大，LDO的瞬态响应性能越好，缺点是会延长启动时间。
在电源的阻抗偏高的情况下，当IC的输入端未接电容或所接电容值很小时，会发生振荡，请加以注意。
2、封装的选择：
SOT23-3的最大额定功率为0.4W，SOT89-3的最大额定功率为1W，SOT23-5的最大额定功率为0.43W，DFN6 2X2的最大额定功率为0.9W，DFN4 1X1的最大额定功率为0.4W。
请注意输入、输出电压以及负载电流的使用条件，避免IC内的功耗超过封装的容许功耗。
3、PCB布线：
重点要考虑噪声、纹波和散热问题，尽可能将输出电容（CL）接在VOUT-VSS管脚的附近，将输入电容（CIN）接在VIN-VSS管脚的附近，LDO和电容要使用同一铜层铺地，尽量增加地面积。
