LT1129IST-5#PBF Description
The LT1129IST-5#PBF is a micropower low dropout regulator with a shutdown. The LT1129IST-5#PBF is capable of supplying 700mA of output current with a dropout voltage of 400mV at maximum output. Designed for use in battery-powered systems, the low quiescent current, 50μA operating and 16μA in shutdown, make it an ideal choice. The quiescent current does not rise in dropout as it does with many other low dropout PNP regulators.
