LND1117
800mA Low Dropout Voltage Regulator
GENERAL DESCRIPTION
The LND1117 series of positive adjustable and fixed regulators are designed to provide 800mA with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 700 mV 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 LND1117 can also be used as a single supply device( 3 pin version). On-chip trimming adjusts the reference voltage to 1%.
