ETQ553ADJYB

General Description

The ETQ553ADJYB is a CMOS-based low-dropout, low-power linear regulators, offering 500mA with low dropout voltage, high ripple rejection, high output accuracy and low supply current. The ETQ553ADJYB consist of an accurate voltage-reference block, an error amplifier, a voltage-setting resistor net, a PMOSFET pass device, a thermal-shutdown circuit, and a current limit circuit with short protection. The ETQ553ADJYB use a type of outstanding CMOS process to minimize the supply current. A low on-resistance PMOS pass device is equipped for lower dropout voltage. ETQ553ADJYB also possess the EN function to save more energy and extend the battery life.
