7.1 Overview

The TPS7A14 is a low-input, ultra-low dropout, low-quiescent-current linear regulator that is optimized for excellent transient performance. These characteristics make the device designed for most battery-powered applications. The low operating VIN – VOUT, combined with the BIAS pin, dramatically improve the efficiency of low-voltage output applications by powering the voltage reference and control circuitry and allowing the use of a pre-regulated, low-voltage input supply (IN) for the main power path. This low-dropout regulator (LDO) offers foldback current limit, shutdown, thermal protection, and an optional active discharge.
