XRP6274
2A Ultra Low Dropout Voltage Regulator
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or above any other of those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum rating
conditions for extended periods of time may affect
reliability.

ELECTRICAL SPECIFICATIONS
Specifications are for an Operating Junction Temperature of TJ = TA = 25°C only; limits applying over the full Operating
Junction Temperature range are denoted by a “•”. Typical values represent the most likely parametric norm at TJ = 25°C,
and are provided for reference purposes only. Unless otherwise indicated, VIN = VOUT + 0.5V and IOUT=20mA, CIN = 47µF, COUT
= 47µF, TA= 25°C.
