Low-dropout linear regulator operates from a 2.7 V to 20 V input and supplies up to 200 mA. The 2.5 V fixed-output option provides 11 µV rms output noise and high PSRR for noise-sensitive analog rails. Initial output accuracy is ±0.8%, with specified accuracy over line, load, and junction temperature to 125°C. The regulator is stable with a 2.2 µF ceramic output capacitor and is offered in LFCSP, SOIC, and TSOT package options.
