Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.Note 3: Line and load regulation are guaranteed up to the maximum power dissapation (60W for the LT1083, 45W for the LT1084 (K, P), 30W for the LT1084 (T) and 30W for the LT1085). Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range.Note 4: I FULL LOAD is defined in the current limit curves. The I FULLLOAD curve is defined as the minimum value of current limit as a function of input-to-output voltage. Note that the 60W power dissipation for theLT1083 (45W for the LT1084 (K, P), 30W for the LT1084 (T), 30W for the LT1085) is only achievable over a limited range of input-to-output voltage. Note 5: Dropout voltage is specified over the full output current range of the device. Test points and limits are shown on the Dropout Voltage curve.Note 6: For LT1083 I FULL LOAD is 5A for –55°C ≤ T J < –40°C and 7.5A for T J≥ –40°C.Note 7: 1.7V ≤ (V IN – V OUT) ≤ 25V for LT1084 at –55°C ≤ T J≤–40°C. Note 8: Dropout is 1.7V maximum for LT1084 at –55°C ≤ T J≤ –40°C.The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at T A = 25°C.345678910APPLICATIO S I FOR ATIO W UU U Connected as shown, R P is not multiplied by the divider ratio. R P is about 0.004Ω per foot using 16-gauge wire.This translates to 4mV/ft at 1A load current, so it is important to keep the positive lead between regulator and load as short as possible and use large wire or PC board traces.Thermal ConsiderationsThe LT1083 series of regulators have internal power and thermal limiting circuitry designed to protect the device under overload conditions. For continuous normal load conditions however, maximum junction temperature rat-ings must not be exceeded. It is important to give careful consideration to all sources of thermal resistance from junction to ambient. This includes junction-to-case, case-to-heat sink interface, and heat sink resistance itself. New thermal resistance specifications have been developed to more accurately reflect device temperature and ensure safe operating temperatures. The data section for these new regulators provides a separate thermal resistance and maximum junction temperature for both the Control Sec-tion and the Power Transistor . Previous regulators, with a single junction-to-case thermal resistance specification,used an average of the two values provided here and therefore could allow excessive junction temperatures under certain conditions of ambient temperature and heat sink resistance. To avoid this possibility, calculations should be made for both sections to ensure that both thermal limits are met.Junction-to-case thermal resistance is specified from the IC junction to the bottom of the case directly below the die.This is the lowest resistance path for heat flow. Proper mounting is required to ensure the best possible thermal flow from this area of the package to the heat sink. Thermalcompound at the case-to-heat sink interface is strongly recommended. If the case of the device must be electri-cally isolated, a thermally conductive spacer can be used,as long as its added contribution to thermal resistance is considered. Note that the case of all devices in this series is electrically connected to the output.For example, using an LT1083CK (TO-3, Commercial) and assuming:V IN (max continuous) = 9V, V OUT = 5V, I OUT = 6A,T A = 75°C, θHEAT SINK = 1°C/W,θCASE-TO-HEAT SINK = 0.2°C/W for K package with thermal compound.Power dissipation under these conditions is equal to:P D = (V IN – V OUT )(I OUT ) = 24W Junction temperature will be equal to:T J = T A + P D (θHEAT SINK + θCASE-TO-HEAT SINK + θJC )For the Control Section:T J = 75°C + 24W (1°C/W + 0.2°C/W + 0.6°C/W) = 118°C 118°C < 125°C = T JMAX (Control Section Commercial Range)For the Power Transistor:T J = 75°C + 24W (1°C/W + 0.2°C/W + 1.6°C/W) = 142°C 142°C < 150°C = T JMAX (Power Transistor Commercial Range)In both cases the junction temperature is below the maximum rating for the respective sections, ensuring reliable operation.11121314Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

LT1085 — 3A 低压差正可调稳压器特点
•三端可调
•输出电流：3A、5A 或7.5A
•可在低至1V 的压差条件下运作
•在多种电流水平条件下提供保证的压差
•电压调整率：0.015%
•负载调整率：0.01%
•进行了全面的热限制功能测试
•可提供固定版本
•提供3 引脚塑料TO-220、TO-3P 和DD 封装
典型应用
描述
LT®1083 系列正可调稳压器专为以高于现有器件的效率来提供7.5A、5A 和3A 输出电流而设计。

所有内部电路均为能够在低至1V 的输入至输出差分电压条件下运作而设计，并且把压差电压作为负载电流的一个函数拟订了全面的规格。

压差在最大输出电流条件下保证为 1.5V (最大值)，并在较低负载电流时有所减小。

片内修整把输出电压准确度调节至1%。

对电流限值也进行了修整，从而最大限度地减小了过载条件下稳压器和电源电路上承受的应力。

LT1083/LT1084/LT1085 器件的引脚与老式三端稳压器兼容。

在这些新型器件上需要布设一个10μF 输出电容器；然而，在大多数稳压器设计中通常已包括该电容器。

与PNP 稳压器(它有多达10% 的输出电流作为静态电流而消耗掉了) 的不同，LT1083 的静态电流将流入负载，从而提升了效率。

应用
•高效率线性稳压器
•用于开关电源的后置稳压器
•恒定电流稳压器
* 对于一个1.5A 的低压差稳压器，请参考LT1086 数据表。

Operating Conditionsare conditions under which the device functions but the specifications might not be guaranteed. For guaranteedspecifications and test conditions see the Electrical Characteristics.Note 2: The maximum power dissipation is a function of the maximum junction temperature, T Jmax ; total thermal resistance,θJA, and ambient temperature T A. The maximum allowable power dissipation at any ambient temperature isT jmax-T A / θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into ther-mal shutdown.Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.Note4: The type of output capacitor should be tantalum or aluminum.DefinitionsDropout VoltageThe input/output Voltage differential at which the regu-lator output no longer maintains regulation against fur-ther reductions in input voltage. Measured when the output drops 2% below its nominal value. Dropout volt-age is affected by junction temperature, load current and minimum input supply requirements.Line RegulationThe change in output voltage for a change in input volt-age. The measurement is made under conditions of low dissipation or by using pulse techniques such that av-erage chip temperature is not significantly affected. Load RegulationThe change in output voltage for a change in load current at constant chip temperature. The measure-ment is made under conditions of low dissipation or by using pulse techniques such that average chip tem-perature is not significantly affected.Maximum Power DissipationThe maximum total device dissipation for which the regulator will operate within specifications.Quiescent Bias CurrentCurrent which is used to operate the regulator chip and is not delivered to the load.V IN-V OUT = 3V, C IN = 220µF, C OUT = 220µF, T A=25°C, unless otherwise noted.Line Transient Response Load Transient ResponseShort Circuit CurrentG1085-33 OvercurrentProtection Characteristics G1085-33 Start-upG1085-18 Overcurrent Protection CharacteristicsG1085-18-Start-upG1085 Max.

(Ground only for Fixed-Mode) The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤ 20Ω) capacitor must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR ≤ 20Ω) is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.4V (1.3V) higher than Vout in order for the device to regulate properly.
