L4938ND DUAL MULTIFUNCTION VOLTAGE REGULATOR

L4938ND DUAL MULTIFUNCTION VOLTAGE REGULATOR

The L4938N is a monolithic integrated dual voltage regulatorswith two very low dropout outputsand additional functions such as power-on reset and input voltage sense. They are designedfor supplying microcomputer controlled systems specially in automotive applications. PIN CONNECTION (top view) POW.

Features

and auxiliary functions are provided to meet the requirements of supplying the microprocessor systems used in automotive applications. Furthermore the device is suitable also in other applications requiring two stabilized voltages. The modular approach allows other features and functions to be realized easily when required. STANDBY REGULATOR The standby regulator uses an Isolated Collector Vertical PNP transistor as the regulating element. This structure allows a very low dropout voltage at currents up to 50mA. The dropout operation of the standby regulator is maintained down to 2V input suppl.
