The MCP1700 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 mA of current while consuming only 1.6 µA of quiescent current (typical). The input operating range is specified from 2.3V to 6.0V, making it an ideal choice for two and three primary cell battery-powered applications, as well as single cell battery-powered applications.
The MCP1700 is a CMOS low‑dropout (LDO) voltage regulator designed for battery‑powered applications. It operates from 2.3 V to 6.0 V input and provides selectable output voltages from 1.2 V to 5.0 V, making it suitable for devices such as PDAs, digital cameras, and microcontroller power supplies.
Key specifications include a typical quiescent current of 1.6 µA, up to 250 mA output current, 0.4 % output‑voltage tolerance, and built‑in short‑circuit and over‑temperature protection. The device is offered in SOT‑23, SOT‑89‑3, and TO‑92 packages.
