The MCP1702 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 mA of current while consuming only 2.0 µA of quiescent current (typical). It is suitable for battery-powered devices, smoke detectors, digital cameras, etc.
The MCP1702 is a CMOS low‑dropout (LDO) voltage regulator that delivers up to 250 mA while consuming only 2 µA of quiescent current. It operates from 2.7 V to 13.2 V input and offers selectable output voltages from 1.2 V to 5.0 V, making it suitable for battery‑powered devices, PDAs, digital cameras, and other low‑power applications.
The device is available in three package types—SOT‑23A, SOT‑89‑3, and TO‑92—and includes built‑in short‑circuit and over‑temperature protection. Detailed electrical specifications, typical performance curves, and temperature data are provided to aid designers in integrating the regulator into their circuits.
