TPS7A8400ARGRT TI LDO Regulator | 20-VQFN (3.5x3.5) | 3A, 0.8V to 5.5V

Product Overview

The TPS7A8400ARGRT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator capable of delivering up to 3A of output current. It operates over a wide input voltage range from 0.8V to 5.5V and provides an adjustable output voltage down to 0.8V with excellent accuracy. Housed in a compact 20-pin VQFN package (3.5mm x 3.5mm), this device is ideal for space-constrained applications requiring high efficiency and low noise.
