EUP7907A

600mA Low Noise High PSRR Low Dropout Linear Regulator DESCRIPTION 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.
