LT1129IS8#TRPBF Description

Short technical summary and product information.

The LT1129IS8#TRPBF is a micropower low dropout regulator designed for battery-powered systems by Analog Devices. It offers a 700mA output current capability with a typical dropout voltage of 400mV. The device operates with a low quiescent current of 50µA, which reduces to 16µA in shutdown mode, conserving power.

 

Key features include an adjustable output voltage ranging from 3.8V to 30V, making it versatile for various applications. It is stable with small output capacitors as low as 3.3µF. The regulator also provides reverse battery protection and no reverse output current flow, making it suitable for backup power situations.

 

This component is available in an 8-SOIC package, designed for surface mounting. Its operating temperature range is -40°C to 125°C. The LT1129IS8#TRPBF is well-suited for low current regulation, battery-powered devices, and post-regulation for switching supplies.
