DATA SHEET
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%.
