DESCRIPTION  
The TPS22933 is a small, low rON, triple-input power  
multiplexer with auto-input selection and a Low  
Drop-Out 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.
