L5962
Voltage regulator with dc-dc plus switchable linear regulators controlled by I2C bus-
Active
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).
