Using the TPS22933AEVM-005 Triple-Input Power
Multiplexer with Auto-Select and Integrated LDO
The TPS22933AEVM-005 evaluation module (EVM) allows the user to source up to 50mA from a fixed
output Low Drop-Out Regulator (LDO) that is sourced by the highest of three inputs (2.5V to 12V). The
EVM has fixed loads for each of the LDO outputs of 1mA and 25mA. The user can also supply an external
load.
