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.
