L4901A Datasheet Dual 5v Regulator With Reset

Manufacturer: STMicroelectronics

Overview: ® L4901A DUAL 5V REGULATOR WITH RESET . . . . . . . . . . . .

General Description

The L4901A 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.

PIN CONNECTION June 2000 1/10 L4901A PIN DESCRIPTION N° 1 2 3 4 5 Name Input 1 Input 2 Timing Capacitor GND Reset Output Output 2 Output 1 Function Low Quiescent Current 400mA Regulator Input.

Key Features

  • : - 5 V internal reference without voltage divider between the output and the error comparator ; - very low drop series regulator element utilizing current mirrors ; permit high output impedance and then very low leakage current error even in power down condi- 4/10 L4901A tion. This output may thereforebe usedto 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 a.
