Product Summary
The LT1129IQ-5 is a micropower low dropout regulator with shutdown. The device is capable of supplying 700mA of output current with a dropout voltage of 0.4V at maximum output. The LT1129IQ-5 is designed for use in battery-powered systems the low quiescent current, 50μA operating and 16mA 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. The applications of the LT1129IQ-5 include: Low Current Regulator, Regulator for Battery-Powered Systems, Post Regulator for Switching Supplies, 5V to 3.3V Logic Regulator.
