The ADP7102 is a 20 V, 300 mA, low noise, CMOS LDO manufactured by Analog Devices. The product features low noise, high accuracy, and low quiescent current.
The ADP7102 is a CMOS low‑dropout linear regulator that operates from 3.3 V to 20 V and delivers up to 300 mA of output current. It offers low noise (15 µV rms), high PSRR (60 dB at 10 kHz), and a dropout voltage as low as 200 mV at full load. The device is available in 7 fixed output voltages and an adjustable version covering 1.22 V to Vin‑Vbo.
Typical applications include precision analog circuits such as ADCs, DACs, amplifiers, high‑frequency oscillators, clocks, PLLs, as well as communications, medical, and industrial instrumentation. The LFCSP and SOIC packages provide a compact footprint and good thermal performance.
