7 Detailed Description

7.1 Overview

The TPS746-Q1 is a low-dropout regulator (LDO) that consumes low quiescent current and delivers excellent

line and load transient performance. These characteristics, combined with low noise and good PSRR with low

dropout voltage, make this device ideal 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 +150°C.
