FEATURES

The LND5203 series of positive adjustable and

fixed regulators are designed to provide 3A 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 LND5203 can also be used as

a single supply device (3-pin version). On-chip

trimming adjusts the reference voltage to 1%.
