The LT1129IQ#TRPBF is a micropower low dropout regulator with shutdown capability, manufactured by LTC. It is designed for battery-powered applications, featuring a low quiescent current of 50μA during operation and 16μA in shutdown mode. This regulator can supply up to 700mA of output current with a typical dropout voltage of 400mV at maximum output.
Key features include stability with small output capacitors as low as 3.3μF, reverse battery protection, and controlled quiescent current in dropout. The device is available in a surface-mount SOT-223 package, making it suitable for space-constrained designs.
Applications for the LT1129IQ#TRPBF include low current regulation, regulators for battery-powered systems, post-regulation for switching supplies, and 5V to 3.3V logic regulation. Its ability to operate with reverse input voltage without reverse current flow from output to input also makes it ideal for backup power situations.
