3A Low Dropout Voltage Regulator


The XRP29302 is a 3A, highly accurate voltage regulator with a low dropout voltage of 600mV (typical) at 3A.

This regulator is specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. It is fully fault protected against overcurrent, reverse battery, and positive and negative voltage transients. On-chip trimming adjusts the reference voltage to 1% initial accuracy.

The XRP29302 is offered in 5-pin TO220 and TO263 packages.
