EUP7905 Datasheet | Eutech Microelectronics

600m A 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 2.2u F ceramic capacitor can make the device stable over the whole load range. The EUP7905 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 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 1.2V~3.6V. Other key Features include over-current protection, thermal shutdown. The device can be available in the TDFN-6 and SOT23-5 package.
