TPS7A02185PDQNR TI LDO Regulator | 4-X2SON(1x1) | 1.85V, 200mA, Ultra-Low Noise

Product Overview

The TPS7A02185PDQNR from Texas Instruments is a high-performance, ultra-low-noise, low-dropout (LDO) linear voltage regulator. It delivers a fixed output voltage of 1.85V with a maximum output current of 200mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), this device is ideal for space-constrained applications requiring clean power rails. The TPS7A02 family features exceptional PSRR (power supply rejection ratio) and low output noise, making it suitable for noise-sensitive circuits such as RF, analog, and precision data converters.
