Monolithic Linear IC 150mA, 5V 5-Pin Voltage Regulator with Reset Function Ordering number:ENN2622B L78LR05 SANYO Electric Co.,Ltd. Semiconductor Company TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN D1599TH (KT)/61093TS/8039YT/5178TA/7067TA, TS No.2622–1/6 Package Dimensions unit:mm 3103 [L78LR05] 1 : INPUT 2 : DELAY CAPACITOR 3 : GND 4 : RESET OUTPUT 5 : OUTPUT SANYO : TP-5H 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 : 2 μA 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).
