L78LR05D

Ordering number:ENN2622B Monolithic Linear IC L78LR05 150mA, 5V 5-Pin Voltage Regulator with Reset Function Overview The L78LR05 is voltage regulator IC that performs the reset 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. VRT rank VRT (V) B 4.8 C 4.5 D 4.2 E 3.9 F 3.6 G 3.3 H 3.0 0.6 Package Dimensions unit:mm 3103 [L78LR05] 1.5 6.5 5.0 2.3 0.5 5.5 7.0 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. 1.2 7.5 0.5 1.3 1.3 1.3 1.3 0.5 1 : INPUT 2 : DELAY CAPACITOR 3 : GND 4 : RESET OUTPUT 5 : OUTPUT SANYO : TP-5H Features 5V, 150mA output. Capable of generating a microcomputer reset signal. No battery-regulator switching circuit required at the battery 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 microcomputers. Especially suited for use as an on-board regulator for a microcomputer system. Small-sized power package TP-5H permitting the equipment to be made compact. The allowable power dissipation can be increased by being surface-mounted o...
