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 heat-sink 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 effective output impedance improvement of typically twoorders of magnitude,along with lower quiescent current and lower noise.L78L00SERIESPOSITIVE VOLTAGEREGULATORSL78L00SERIES2/24ABSOLUTE MAXIMUM RATINGS(*)Our SO-8package used for Voltage Regulators is modified internally to have pins 2,3,6and 7electrically communed to the die attach flag.This particular frame decreases the total thermal resistance of the package and increasesits ability to dissipate power when an appro-priate area of copper on the printed circuit board is available for heat-sinking.The external dimensions are the same as for the standard SO-8.THERMAL DATA(*)Considering 6cm of copper Board heat-sinkTEST CIRCUITSCONNECTION DIAGRAM (top

General Description
The TS78L00 Series of positive voltage Regulators are inexpensive, easy-to-use devices suitable for a multitude of applications that require a regulated supply of up to 100mA. Like their higher power TS7800 and TS78M00 Series cousins, these regulators feature internal current limiting and thermal shutdown making them remarkably rugged. No external components are required with the TS78L00 devices in many applications. These devices offer a substantial performance advantage over the traditional zener diode-resistor combination, as output impedance and quiescent current are substantially reduced.

LM7818中文资料目录1.lm7818介绍2.实际应用3.引脚序号、引脚功能4.lm7818应用电路5.7818电参数三端稳压集成电路lm7818。

电子产品中，常见的三端稳压集成电路有正电压输出的lm78 ×× 系列和负电压输出的lm79××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。

它的样子象是普通的三极管，TO- 220 的标准封装，也有lm9013样子的TO-92封装。

1.lm7818介绍用lm78/lm79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lm78或lm79后面的数字代表该三端集成稳压电路的输出电压，如lm7806表示输出电压为正6V，lm7909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。

最大输出电流1.5A，LM78XX系列输出电压分别为5V;6V;8V;9V;10V;12V;15V;18V;24V。

2.实际应用在实际应用中，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7818IC内部电路图.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lm78 ** 、lm79 ** 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。

图中的引脚号标注方法是按照引脚电位从高到底的顺序标注的。
