CMPWR300 - 500mA SMARTOR Dual Regulator

Description

The CMPWR300 is a dual input regulator with VAUX switch capable of delivering 3.3V/500mA continuously.

The output power is provided from three independent input voltage sources on a prioritized basis.

Power is always taken in priority using the following order VCC, VSBY, and VAUX.

Features

  • • 8-pin Power SOIC package • Continuous 3.3V output from three inputs • Complete Power Management solution • VCC, VSBY Regulator supplies 500mA output • Built-in hysteresis when selecting input supplies • Integrated switch has very low RDS(ON) 0.12Ω (typ. ) • Large Bypass Capacitors on inputs not required Pin Diagram.
