6 Detailed Description

6.1 Overview

The TPS737 is a low-dropout (LDO) regulator that uses an n-type field effect (NMOS) pass transistor to achieve

ultra-low dropout performance, reverse current blockage, and freedom from output capacitor constraints. These

features combined with an enable input make the TPS737 designed for portable applications. This regulator

offers a wide selection of fixed-output voltage versions and an adjustable-output version. All versions have

thermal and overcurrent protection, including foldback current limit.
