Monolithic Linear IC
L78LR05
150mA, 5V 5-Pin Voltage Regulator
with Reset Function
Overview
The L78LR05 is voltage regulator IC that performs the re-
set signal generating function when the power supply of a
microcomputer system is turned ON/OFF. The L78LR05
is convenient for battery backup system at the time of power
failure. The reset threshold voltage VRT is ranked as shown
below.

Applications
• Prevention of malfunction that may occur when the power
supply of a microcomputer is turned ON/OFF.
• Measures taken against abnormal operations that may
occur at the time of instantaneous break of power supply.
• Direct battery backup for SRAM.
Features
• 5V, 150mA output.
• Capable of generating a microcomputer reset signal.
• No battery-regulator switching circuit required at the bat-
tery backup mode (Output leakage current : 2µA or less).
• An external capacitor can be used to set the reset output
delay time.
• Applicable to the power supply of CMOS, NMOS micro-
computers.
• Especially suited for use as an on-board regulator for a
microcomputer system.
• Small-sized power package TP-5H permitting the equip-
ment to be made compact.
• The allowable power dissipation can be increased by be-
ing surface-mounted on the board.
• Capable of being mounted in a variety of methodes be-
cause of various lead forming versions available.
• On-chip protectors (overcurrent limiter, ASO protector,
thermal protector).
