500mA, 3.3V Linear Regulator with Auxiliary Control

Description The CS5231-3 combines a threeterminal linear regulator with circuitry to control an external PFET transistor with the intent of managing two input supplies. A 5V supply powers the regulator while an auxiliary 3.3V supply is controlled by the IC. The design has been optimized to provid

500 mA, 3.3 V Linear Regulator with Auxiliary Control

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
