LM78XX May 2000 Series LM78XXSeries Voltage Regulators V General Description put, although this does improve transient response. Input by- oltage passing is needed only if the regulator is located far from the The LM78XX series of three terminal regulators is available filter capacitor of the power supply. with several fixed output voltages making them useful in a For output voltage other than 5V, 12V and 15V the LM117 wide range of applications. One of these is local on card series provides an output voltage range from 1.2V to 57V. regulation, eliminating the distribution problems associated Regulators with single point regulation. The voltages available allowthese regulators to be used in logic systems, instrumenta- Features tion, HiFi, and other solid state electronic equipment. Al- n Output current in excess of 1A though designed primarily as fixed voltage regulators these n Internal thermal overload protection devices can be used with external components to obtain ad- n No external components required justable voltages and currents. n Output transistor safe area protection The LM78XX series is available in an aluminum TO-3 pack- n Internal short circuit current limit age which will allow over 1.0A load current if adequate heat n Available in the aluminum TO-3 package sinking is provided. Current limiting is included to limit thepeak output current to a safe value. Safe area protection for Voltage Range the output transistor is provided to limit internal power dissi-pation. If internal power dissipation becomes too high for the LM7805C 5V heat sinking provided, the thermal shutdown circuit takesover preventing the IC from overheating.
