EUP7907-XXVIR1 数据手册
EUP7907 600mA 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 2.2uF 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. EUP7907 can be operated in two modes, operated in fixed mode when the FB pin connected to ground, its output is a pre-set value:0.8V~3.6V. There is no external component needed to decide the output voltage. Operated in adjustable mode when the FB pin 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. FEATURES 2.5V to 5.5V Input Voltage Range 300mV@600mA Dropout Voltage Excellent Transient Response Stable with 2.2uF Ceramic Output Capacitor 70dB PSRR at 1kHz Low 120µA Quiescent Current Low Shutdown Current:
