L4904A - DUAL 5V REGULATOR WITH RESET

Description

The L4904A is a monolithic low drop dual 5V regulator designed mainly for supplying microprocessor systems.

Reset and data save functions during switch on/off can be realized.

N° 1 2 3 4 5 6 Name Input 1 Input 2 Timing Capacitor GND N.C.

Features

  • : - 5 V internal reference without voltage divider between the output and the error comparator ; - very low drop series regulator element utilizing mirrors ; permit high output impedance and then very low leakage current even in power down conditions. This output may thereforebe used to supply circuits continuously, such as volatile RAMs, allowing the use of a back-up battery. The V01 regulator also features low consumption (0.6 mA typ. )to minimize battery drain in.
