NCP1117LP
1.0 A Low-Dropout Positive
Fixed and Adjustable
Voltage Regulators
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.
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 package.
