Overview
The TPS7A7200RGWT is a 2-A, fast-transient, low-dropout voltage regulator produced by Texas Instruments. This device is designed for applications requiring very-low dropout capability, with an input voltage range of 1.5 V to 6.5 V. It offers a user-configurable output voltage setting from 0.9 V to 3.5 V, eliminating the need for external resistors and associated errors. The regulator is known for its fast load-transient response, stability with ceramic output capacitors, and high accuracy over line, load, and temperature.
