LT1129IS8#TRPBF Description

Short technical summary and product information.

The LT1129IS8#TRPBF is a micropower low dropout regulator designed by Analog Devices (formerly Linear Technology). This device is capable of supplying up to 700mA of output current with a typical dropout voltage of 400mV. Its low quiescent current of 50µA during operation and 16µA in shutdown makes it suitable for battery-powered applications.

 

Key features include stability with small output capacitors (as low as 3.3µF) and reverse battery protection, allowing it to be used in backup power situations. The regulator operates over an input voltage range of 4.15V to 30V and provides an adjustable output voltage from 3.8V to 30V.

 

This specific part is supplied in an SO-8 package, suitable for surface mounting. The device also features thermal limiting for protection against overcurrent and overheating conditions.
