GENERAL DESCRIPTION

The LND5201 series of positive adjustable and fixed regulators are designed to provide 1A with higher efficiency than currently available devices. All internal circuitry are 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 LND5201 can also be used as a single supply device (3-pin version). On-chip trimming adjusts the reference voltage to 1.
