SLVSB34A – OCTOBER 2011 – REVISED JUNE 2015 TPS22933 Triple-Input Power Multiplexer With Auto-Select and Low Drop-Out Voltage
Regulator
1 Features 3 Description The TPS22933 device is a small, low rON, triple-input
power multiplexer with auto-input selection and a lowdropout linear regulator. The device contains three Pchannel 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. 1 Three Integrated Load Switches Automatically
