EUP7907

600mA High PSRR Low Dropout

Linear Regulator

DESCRIPTION

FEATURES

The EUP7907 is a high current, low dropout 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 EUP7907 is designed to work with low-ESR ceramic

capacitor, reducing the amount of the PCB area necessary for

power applications. Only a 2.2uF ceramic capacitor can

make the device stable over the whole load range.

The EUP7907 monitors the input voltage for power on reset

to ensure the regulator is disabled when the input voltage is

not high enough for normal operation. When EUP7907

detects fault signal, such as over-temperature, it will turn off

the pass transistor and discharge VOUT to GND from the

internal resistor.

EUP7907 can be operated in two modes, operated in fixed

mode when the FB pin connected to ground, its output is a

pre-set value:0.8V~3.6V. There is no external component

needed to decide the output voltage. Operated in adjustable

mode when the FB pin connected to two external resistors

divider, its output can be adjusted from 0.8V to 5V. Other

key features include over-current protection, thermal

shutdown. The device can be available in the TDFN-8

package or SOT23-5 package.
