TPS7A20L28PDQNR TI LDO Regulator | 4-X2SON (1x1) | 2.8V Output, 300mA

Product Overview

The TPS7A20L28PDQNR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 2.8V with a maximum output current of 300mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), this device is designed for space-constrained applications requiring high accuracy and low noise. With an ultra-low dropout voltage of typically 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The TPS7A20L28PDQNR features a wide input voltage range from 1.6V to 5.5V, making it suitable for battery-powered and portable electronics.
