LM78M12中⽂资料LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess

fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125?C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of Conduction Pins Placement of Mounting Pad Die SizePCB Size

regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0?C to 125?C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN ?V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ?C/w is found to be ≥60?C/W for TO-220package or ≥92?C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in

LM7815中文资料目录1.lm7815介绍2.实际应用3.引脚序号、引脚功能4.lm7815应用电路5.7815电参数三端稳压集成电路lm7815。

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.lm7815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7815IC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。
