SERIES REGULATOR WITH RESET FUNCTION
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM78LR05 is a series regulator with reset
function.
In case of shut down or output voltage drop, the IC
generates reset signal to a microcomputer.
That is suitable for items with microcomputer, such
as TV sets, remote controller, refrigerator and others.
■ FEATURES
● Output Current I
O
=150mA max.
● Reset Function Including

by an External Capacitance.
● Internal Over Current Protection
● Thermal Shut Down
● Bipolar Technology
● package Outline DIP8, DMP8, SIP8, SOT-89 (5Pin)
