TPS79925DDCR 200mA Ultra‑Low Noise LDO Regulator
The TPS79925DDCR is a high‑performance fixed‑output low‑dropout (LDO) linear regulator from Texas Instruments, delivering a precise 2.5V output at up to 200mA for noise‑sensitive analog and radio‑frequency (RF) circuits. Packaged in a thin, space‑saving SOT‑23‑5 (TSOT‑23‑5) surface‑mount enclosure, it operates from 2.7V to 6.5V input, features a typical dropout voltage of only 180mV at full load, and maintains tight ±2% output accuracy across line, load, and temperature variations. Designed with an advanced BiCMOS process, this LDO combines ultra‑low noise, high power‑supply rejection ratio (PSRR), and minimal quiescent current, making it ideal for battery‑powered and high‑precision systems requiring clean, stable power rails.
Key Features & Application Scenarios
This regulator boasts ultra‑low noise (29.5 µV RMS), high PSRR (70dB at 100Hz, 38dB at 100kHz), and a fast 45µs start‑up time, ensuring exceptional noise suppression and rapid power‑on response. It draws a mere 40–60µA quiescent current, includes an enable pin for on/off control, and is stable with low‑ESR ceramic capacitors (2µF typical), simplifying external component selection. Built‑in protection features comprise thermal shutdown, overcurrent limiting, and reverse‑polarity protection, enhancing system durability in harsh conditions. The operating temperature range spans −40°C to +125°C, supporting industrial and consumer applications. Core uses include RF transceivers, ADC/DAC modules, portable medical devices, wireless sensors, battery‑powered electronics, and precision analog circuits.
