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

三端稳压器78xx79xx系列芯片介绍
三端稳压器78xx79xx系列芯片介绍关键词：电路介绍三端稳压电子产品中常见到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。
故名思义，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9013样子的TO-92 封装。
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。
78/79系列三端稳压IC 有很多电子厂家生产，80年代就有了，通常前缀为生产厂家的代号，如TA7805是东芝的产品，AN7909是松下的产品。
（点击这里，查看有关看前缀识别集成电路的知识）有时在数字78或79后面还有一个M或L，如78M12或79L24，用来区别输出电流和封装形式等，其中78L调系列的最大输出电流为100mA ，78M系列最大输出电流为1A，78系列最大输出电流为1．5A。
它的封装也有多种，详见图。
塑料封装的稳压电路具有安装容易、价格低廉等优点，因此用得比较多。
79系列除了输出电压为负。
引出脚排列不同以外，命名方法、外形等均与78系列的相同。
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，可以用来改装至⒃??奈妊沟缭矗?簿?Ｓ米鞯缱由璞傅墓ぷ鞯缭础５缏吠既缤妓?尽?注意三端集成稳压电路的输入、输出和接地端绝不能接错，不然容易烧坏。
一般三端集成稳压电路的最小输入、输出电压差约为2V，否则不能输出稳定的电压，一般应使电压差保持在4-5V，即经变压器变压，二极管整流，电容器滤波后的电压应比稳压值高一些。
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）。
