L4902A - DUAL 5V REGULATOR WITH RESET AND DISABLE

Description

The L4902A is a monolithic low drop dual 5V regulator designed mainly for supplying microprocessor systems.

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

Features

  • : - 5V 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 even in power down condition. 4/9 L4902A This output may thereforebe usedto supply circuits continuously, such as volatile RAMs, allowing the use of a back-up battery. The V02 output can supply other non essential 5 V circuits which may be powered down when the system is in.
