Dual Input Low Dropout Voltage Regulator

The PJ1581/PJ1582/PJ1583 family is a positive adjustable and fixed voltage regulator developed to provide 5A, 3A, 1.5A with Higher efficiency than currently available devices. All internal circuit is designed to operate down to 700mV input to output differential and the dropout voltage is fully specified as a function of load current. Dropout voltage of the device is 100mV at light loads and rising to 700mV at maximum output current. A Second low current input is required to achieve this dropout. The PJ1581/PJ1582/PJ1583 family is designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back.
