600m A High PSRR Low Dropout Linear Regulator DESCRIPTION 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 2.2u F 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. The EUP7907 has two modes of operation. When the FB pin is connected to ground, its output is a pre-set value: 0.8V~3.6V. There is no external ponent needed to decide the output voltage. When the version of EUP7907 with fixed voltage higher than 1.5V is selected and its FB pin is 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.
