Triple output multifunction voltage regulator

for car radio with IDR/class2 interface

Datasheet

- production data

Features

 3 voltage regulators:

– 3.3 V (100 mA) standby regulator

– 5 V (100 mA) stand-by regulator

– 7.8 V (100 mA)

 Out of regulation detection for 5 V standby

regulator

 Wide operating supply voltage range from

4.5 V up to 26.5 V for transient 34 V

 Very low standby quiescent current (<150 µA)

 Input to output signal transfer function

programmable

 LVS function

 TTL and CMOS compatible inputs

 Output current limitation

 Controlled output slope for low EMI

 Overtemperature shut-down

 Able to survive under loss of ground or battery

 ESD protected

Description

The L5951 is a monolithic triple regulator

integrated with a SAE J1850 Integrated Driver /

Receiver realized in advanced Multipower-BCD

technology. It is intended to drive single wire

J1850 communications, and offer microcontroller

power and power management for automotive or

industrial applications.
