Multiple Linear/Switching Voltage Regulator 36-Pin PowerSO Slug Up Tray

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).

Step-down synchronous switching voltage regulator

Internal high-side/ Low-side NDMOS

1.2 < V_out < 8 V selectable through external resistors

1.2/2.5 A load current selected through dedicated pin
