7.1 Overview

The TPS745 low-dropout regulators (LDO) 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. The internal power-good detection circuit allows the down-stream supplies to be sequenced and alerts if the output voltage is below a regulation threshold.

This regulator offers foldback current limit, shutdown, and thermal protection. The operating junction temperature for this device is –40°C to +125°C.
