XRP29302 Datasheet, PDF (1/9 Pages) Exar Corporation – 3A Low Dropout Voltage Regulator

November 2013
GENERAL DESCRIPTION
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 over-current,
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 TO-220 &
TO-263 packages.
