The input operating range is specified up to 10V, making it ideal for lithium-ion (one or two cells), 9V alkaline and other two and three primary cell battery-powered applications. The MCP1701 is capable of delivering 250 mA with an input-to-output voltage differential (dropout voltage) of 650 mV. The low dropout voltage extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum VIN – VOUT differentials. The MCP1701 has a tight tolerance output voltage regulation of ±0.5% (typical) and very good line regula- tion at ±0.2%. The LDO output is stable when using only 1 µF of output capacitance of either tantalum or aluminum-electrolytic style capacitors. The MCP1701 LDO also incorporates short-circuit protection to ensure maximum reliability. Package options include the 3-Pin SOT-23A, 3-Pin SOT-89 and 3-Pin TO-92.
