The LT1121IST-3.3#TRPBF is a micropower low dropout linear voltage regulator designed for battery-powered applications. It provides a stable 3.3V output and can supply up to 150mA of current with a typical dropout voltage of 0.4V.
Key features include a low quiescent current of 30µA during operation and 16µA in shutdown mode, making it ideal for power-sensitive designs. The regulator is stable with small output capacitors, as low as 0.33µF, enhancing manufacturability. It also offers reverse battery protection and no reverse current flow when the input is low.
This device is available in a surface mount SOT-223-3 package, suitable for compact electronic designs. The operating temperature range is -40°C to 125°C, ensuring reliable performance in various environments. The regulator includes an enable (shutdown) control feature.
Applications include low current regulation, battery-powered systems, and post-regulation for switching supplies. Its robust design and low power consumption make it a versatile choice for portable electronics.
