TPS7A2128PYWDJ TI LDO Regulator | 4-WCSP (0.63x0.63) | 1.8V Output, 500mA

Product Overview

The TPS7A2128PYWDJ is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 500mA. Housed in a compact 4-pin WCSP package measuring 0.63mm x 0.63mm, this device is ideal for space-constrained applications requiring high power supply rejection ratio (PSRR) and low noise. The TPS7A2128 offers excellent transient response and stability with small ceramic output capacitors, making it suitable for powering sensitive analog and RF circuits.
