General Description

L5962 is a very versatile device exploiting BCD technology characteristics to provide a complete set of regulated voltages covering all the needs of a car-radio set.

In standby condition the device guarantees extremely low quiescent current (90 µA max 40 °C < T < 85 °C) and minimum operating voltage (4.5 V using an external Schottky diode for the back-up function).
