The LT1129IQ#TRPBF from Analog Devices is a micropower low dropout regulator with shutdown capability. It is designed for battery-powered systems, offering a low quiescent current of 50µA during operation and 16µA in shutdown. This regulator can supply up to 700mA of output current with a dropout voltage of 400mV at maximum output.
The device features an adjustable output voltage ranging from 3.8V to 30V, and fixed 3.3V and 5V versions are also available. It is stable with a small output capacitor of 3.3µF, simplifying circuit design. The LT1129IQ#TRPBF includes reverse battery protection and no reverse output current flow, making it suitable for backup power situations.
Packaged in a 5-DDPAK surface mount package, this regulator is suitable for various applications including low current regulation, battery-powered devices, and post-regulation for switching supplies. Its operating temperature range is -40°C to 125°C.
