ADP1752/ADP1753 is a low VIN, low dropout linear regulator with a maximum output current of 0.8 A, an input voltage range of 1.6 V to 3.6 V, a shutdown current of less than 2 μA, and a dropout voltage of less than 70 mV. The initial accuracy is ±1%, and the line, load, and temperature accuracy is ±2%.
The ADP1752 and ADP1753 are low‑Vin, low‑dropout CMOS linear regulators that operate from 1.6 V to 3.6 V and deliver up to 0.8 A of output current. They are offered in a 16‑lead LFCSP package (4 mm × 4 mm) and feature high PSRR, low output noise, and built‑in protection functions such as current‑limit, thermal shutdown and reverse‑current protection.
The document provides detailed specifications, pin configurations, recommended capacitor selections, thermal data, and typical performance graphs. It also includes an ordering guide with part numbers for fixed‑output and adjustable‑output versions, as well as evaluation board options.
