Overview

EUP7903 300mA High PSRR LDO Regulators DESCRIPTION The EUP7903 is a high current, low-dropout (LDO) linear regulator with fast transient response and high PSRR.
It offers high output accuracy, extremely low dropout voltage, low quiescent current and fast start-up time.
The EUP7903 is designed to work with low-ESR ceramic capacitors, reducing the amount of the PCB area necessary for power applications.
Only a 1uF ceramic output capacitor can make the device stable over the whole load range.
EUP7903 can be externally set either fixed output mode or adjustable output mode.
Connect FB pin to GND to select the fixed output mode.
Its output is one of pre-set values: 1.
25V~5V (50mV per step).
Operated in the adjustable mode when the FB pin is connected to an external resistors divider, its output can be adjusted from 1.
25V to 5V.
Other key features include over-current protection, thermal shutdown.
The device is available in the small SOT23-5 package.
