The LT1129IST-5 is a micropower low dropout regulator with shutdown capability, designed for battery-powered systems. It can supply up to 700mA of output current with a dropout voltage of 400mV at maximum output. The device operates with a low quiescent current of 50µA, which does not rise in dropout.
Key electrical specifications include a fixed 5V output voltage, a maximum output current of 700mA, and a maximum dropout voltage of 0.7V at 700mA. It also features a PSRR of 64dB at 120Hz and a quiescent current of 50µA during operation and 16µA in shutdown. The input voltage can be up to 30V.
Designed for stability with small output capacitors, the LT1129IST-5 is suitable for applications requiring a reliable voltage source. It offers protection features such as over-temperature and reverse polarity protection. The device is available in a surface mount SOT-223-3 package.
This regulator is ideal for low current applications, battery-powered systems, and as a post regulator for switching supplies. Its features make it a good choice for 5V to 3.3V logic regulation and 5V supplies with shutdown control.
