EUP7907A

600mA Low Noise High PSRR

Low Dropout Linear Regulator

DESCRIPTION

FEATURES

The EUP7907A 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 EUP7907A 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 EUP7907A 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

EUP7907A detects fault signal, such as over-temperature, it

will turn off the pass transistor and discharge VOUT to GND

from the internal resistor.

EUP7907A only can be operated in fixed mode, the pre-set

valve is from 1.2V~3.6V. By setting the capacitor connected

to BYPASS pin can get high PSRR. Other key features

include over-current protection, thermal shutdown. The

device can be available in the TDFN-6 and SOT23-5

package.
