FEATURES
L78L00 Series
GENERAL DESCRIPTION
This Series of fixed-voltage monolithic integrated circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with singlepoint regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal shutdown features of these regulators male them essentially immune to overload. When used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtain -ed together with lower-bias current.
3-terminal regulators Output current up to 100 mA No external component Internal thermal overload protection Internal short-circuit current limiting Direct replacements for LM78L00, A78L00 and AN78L00 series

ABSOLUTE MAXIMUM RATINGS
PARAMETER Input Voltage - V I Continuous total power dissipation Storage Temperature Range - TSTG Junction Temperature - TJ Lead Temperature (Soldering, 10 Seconds) - TL VALUE 30V (See Note 1) -65 to +150 °C 125 °C 260 °C
Note1: To avoid exceeding the design maximum virtual junction temperature, three ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.
DISSIPATION RATING TABLE 1 - FREE-AIR TEMPERATURE
The TO-92 package dissipation rating is based on thermal resistance JA measured in still air with the device mounted in an Augat socket. The bottom of the package is 10mm (0.375 in) above the stock.
