Product Summary
The LT1129CS8-3.3#TR is a micropower low dropout regulator with shutdown. The LT1129CS8-3.3#TR 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, 50uA operating and 16uA in shutdown, make the LT1129CS8-3.3#TR an ideal choice. The quiescent current does not rise in dropout as it does with many other low dropout PNP regulators. The LT1129CS8-3.3#TR applications are: (1)Low Current Regulator; (2)Regulator for Battery Powered Systems; (3)Post Regulator for Switching Supplies; (4)5V to 3.3V Logic Regulator.
