LT1521IS8-5 Description

Short technical summary and product information.

The LT1521IS8-5 is a low dropout regulator designed for battery-powered systems, offering micropower quiescent current and shutdown capabilities. It can supply up to 300mA of output current with a low dropout voltage of 0.5V. The quiescent current is 12mA during operation and drops to 6mA in shutdown mode, making it ideal for power-sensitive applications.

 

This regulator is stable with small output capacitors as low as 1.5µF, enhancing manufacturability. It also features reverse battery protection and no reverse current flow, making it suitable for backup power situations. The LT1521 series offers fixed output voltages including 5V, and adjustable output from 3.8V to 20V.

 

The LT1521IS8-5 is available in an S8 package, suitable for surface mount applications. Its design considerations include controlled quiescent current in dropout and thermal limiting for protection.
