Texas Instruments  TPS22933ARSET

The TPS22933 device is a small, low rON, triple-input power multiplexer with auto-input selection and a low-dropout linear regulator. The device contains three P-channel MOSFETs that can operate over an input voltage range of 2.5 V to 12 V. The TPS22933 automatically selects the highest level (from BAT, USB, and DC_IN) and enables that input to source the LDO. LOUT is an always-on output from the LDO. The Enable function (EN pin) allows VOUT to be switched on or off, enables a quick discharge resistor, and is capable of interfacing directly with low-voltage control signals.

The TPS22933 is available in a small, space-saving 8-pin µQFN package and is characterized for operation over the free-air temperature range of –40°C to 85°C.
