EUP7905

600mA High PSRR Low Dropout Linear Regulator

Description

The EUP7905 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 EUP7905 is designed to work with low-ESR ceramic capacitor, reducing the amount of the PCB area necessary for power applications. Only a 2.2μF ceramic capacitor can make the device stable over the whole load range.

When EUP7905 detects fault signal, such as over-temperature, it will turn off the pass transistor and discharge VOUT to GND from the internal resistor.

EUP7905 only can be operated in fixed mode, the pre-set valve is from 0.8V~3.6V. Other key features include over-current protection, thermal shutdown. The device can be available in the SOT23-5 package.
