NCP1117LP
1.0 A Low-Dropout Positive
Fixed and Adjustable
Voltage Regulators
The NCP1117LP is the low power version of the popular NCP1117
family of low dropout voltage regulators, with reduced quiescent
current. It is intended primarily for high volume consumer
applications over the 0 to 125 degree temperature range. Capable of
providing an output current in excess of 1 A, with a dropout voltage of
1.3 V at 1 A full current load, the series consists of an adjustable and
five fixed voltage versions of 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V.
Internal protection features consist of output current limiting and
built−in thermal shutdown. The NCP1117LP series can operate up to
18 V max input voltage. The device is available in the popular
SOT−223 and DPAK packages.
