CS5231-3 - 3.3V Linear Regulator
CS5231 3 500 mA, 3.3 V Linear Regulator with Auxiliary Control The CS5231 3 combines a three terminal linear regulator with circuitry controlling an external PFET transistor thus managing two input supplies.
The part provides a 3.3 V regulated output either from the main 5.0 V supply or a 3.3 V auxiliary that switches on when the 5.0 V supply is not present.
This delivers constant, uninterrupted power to the load.
