7 Detailed Description

7.1 Overview

The TLV743P device belongs to a new family of next-generation, low-dropout regulators (LDOs). This device

consumes low quiescent current and delivers excellent line and load transient performance. These

characteristics, combined with low noise, good PSRR with low-dropout voltage, make this device well-suited for

portable consumer applications.

This regulator offers foldback current limit, shutdown, and thermal protection. The operating junction temperature

for this device is –40°C to +125°C.
