DATA SHEET
LND5203
3 A Low Dropout Positive Voltage Regulator
GENERAL DESCRIPTION
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%.
