做稳压电源必看的资料-简单实用.

LM2596与LM2577组成的双路稳压电源1.1基本组成电源变压器：采用降压变压器将电网交流电压220V变换成复合需要的交流电源。

此交流电压经过整流后可获得电子设备所需要的直流电压.整流电路：利用单相桥式整流电路把方向和大小都变化的50Hz的交流电变换为方向不变但大小仍有脉动的直流电.其优点是电压较高，纹波电压较小，整流二极管所承受的最大反向交流电流流过，变压器的利用率高.滤波电路：利用储能元件—电容C两端的电压不能突变的性质，采用RC滤波电路将整流电路输出的脉动成分大部分滤除，得到比较平滑的直流电.稳压电路：使整流滤波后的直流电压不随交流电网和负载的变化扰动而变化由于采用大量高性能的集成模块，从而简化了电路的结构，突出了电源变换问题中的关键部分。

通过努力的调试与检测，电路整体性能良好,可以较好的实现设计目的。

本电源不仅可以单独使用，还可以置于其它电子设备中作为变压稳压或稳流源使用。

2电源概述2。

1电源简介电源是电子设备的心脏部分,其质量的好坏直接影响着电子设备的可靠性，而且电子设备的故障60%来自电源，因此作为电子设备的基础元件，电源受到越来越多的重视。

现代电子设备使用的电源大致有线性稳压电源和开关稳压电源两大类.所谓线性稳压电源，是指在稳压电源电路中的调整管是工作在线性放大区。

将220V、50Hz的工频电压经过线性变压器降压以后，经过整流、滤波和稳压，输出一个直流电压。

2。

2两类电源比较线性稳压源的优点是：电源稳定度及负载稳定度较高;输出纹波电压小；瞬态响应速度快；线路结构简单，便于维修；没有开关干扰。

缺点是：功耗大、效率低，其效率一般只有35～60%；体积大、质量重、不能微小型化;必须有较大容量的滤波电容。

其中,交换效率低下是线性稳压电源的重要缺点，造成了资源的严重浪费。

在这种背景下，开关稳压电源应运而生.任何电子设备均需直流电源来供给电路工作。

特别是采用电网供电的电子产品。

为了适应电网电压波动和电路的工作状态变化,更需要具备适应这种变化的直流稳压电源。

COMPONENTS ARE REQUIREDsAVAILABLEIN EITHER ±5%(AC)OR ±10%(C)SELECTIONDESCRIPTIONThe L78L00series of three-terminal positive regulators employ internal current limiting and thermal shutdown,making them essentially indestructible.If adequate heatsink is provided,they can deliver up to 100mA output current.They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation.In addition,they can be used with power pass elements to make high-current voltage regulators.The L78L00series used as Zener diode/resistor combination replacement,offers an effectiveBLOCK DIAGRAMSO-8TO-92output impedance improvement of typically two orders of magnetude,along with lower quiescent current and lower noise.SOT-891/19ABSOLUTE MAXIMUM RATINGSymbol ParameterValue Unit V iDC Input VoltageV o =3.3V to 9V 30V V o =12V to 15V 35V V o =18V to 24V40V I o Output Current

SO-8package used for Voltage Regulators is modified internally to have pins 2,3,6and 7electrically commoned to the die attach flag.This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate area of copper on the printed circuit board is available for heatsinking.The external dimensions are the same as for the

LM78LXX Series3-Terminal Positive RegulatorsGeneral DescriptionThe LM78LXX series of three terminal positive regulators isavailable with several fixed output voltages making themuseful in a wide range of applications.When used as a zenerdiode/resistor combination replacement,the LM78LXX usu-ally results in an effective output impedance improvement oftwo orders of magnitude,and lower quiescent current.Theseregulators can provide local on card regulation,eliminatingthe distribution problems associated with single point regula-tion.The voltages available allow the LM78LXX to be used inlogic systems,instrumentation,HiFi,and other solid stateelectronic equipment.The LM78LXX is available in the plastic TO-92(Z)package,the plastic SO-8(M)package and a chip sized package(8-Bump micro SMD)using National’s micro SMD packagetechnology.With adequate heat sinking the regulator can de-liver100mA output current.Current limiting is included tolimit the peak output current to a safe value.Safe area pro-tection for the output transistors is provided to limit internalpower dissipation.If internal power dissipation becomes toohigh for the heat sinking provided,the thermal shutdown cir-cuit takes over preventing the IC from overheating.Featuresn LM78L05in micro SMD packagen Output voltage tolerances of±5%over the temperaturerangen Output current of100mAn Internal thermal overload protectionn Output transistor safe area protectionn Internal short circuit current limitn Available in plastic TO-92and plastic SO-8low profilepackagesn No external componentsn Output

三端稳压器的作用是什么？三端稳压器7805应用详解

三端稳压器的作用是什么？三端稳压器7805应用详解三端稳压器的作用一般用于直流电路的保护电路，起到降压、稳压的作用。

+常用的78系列和79系列，78XX的都是正电压输出，79XX的都是负电压输出，输入电压一般不要太大，低于36V以内。

+78、79后面经常出现L或H或空白代表额定电流，如78L12代表输出%2B12V+0.5A的电压。

+接线：字面向自己时，最左边是1脚，中间是2脚，最右边是3脚.接线时1脚接电压输入，2脚接c端，3脚接输出端。

7805三端稳压集成电路，电子产品中，常见的三端稳压集成电路有正电压输出的78 系列和负电压输出的79 系列。

顾名思义，三端IC是指这种稳压用的集成电路，只有三条引脚输出，分别是输入端、接地端和输出端。

它的样子像是普通的三极管，TO- 220 的标准封装，也有9013样子的TO-92封装。

组成结构用78/79系列三端稳压IC来组成稳压电源所需的外围元件极少，电路内部还有过流、过热及调整管的保护电路，使用起来可靠、方便，而且价格便宜。

该系列集成稳压IC型号中的78或79后面的数字代表该三端集成稳压电路的输出电压，如7806表示输出电压为正6V，7909表示输出电压为负9V。

因为三端固定集成稳压电路的使用方便，电子制作中经常采用。

在实际应用中，应在三端集成稳压电路上安装足够大的散热器（当然小功率的条件下不用）。

当稳压管温度过高时，稳压性能将变差，甚至损坏。

当制作中需要一个能输出1.5A以上电流的稳压电源，通常采用几块三端稳压电路并联起来，使其最大输出电流为N个1.5A，但应用时需注意：并联使用的集成稳压电路应采用同一厂家、同一批号的产品，以保证参数的一致。

另外在输出电流上留有一定的余量，以避免个别集成稳压电路失效时导致其他电路的连锁烧毁。

在78 ** 、79 ** 系列三端稳压器中最常应用的是TO-220 和TO-202 两种封装。

这两种封装的图形以及引脚序号、引脚功能如附图所示。
