General Description

The MCP1701 is a f amily o f CM OS low d rop out (LDO ), positive voltage regulators that can deliver up to 250 mA of current while consuming only 2.0 µA of quiescent current (typ.). 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-power ed app lic ati on s.

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 als o perm its high currents in small packages when operated with minimum V differentials.

The MCP1701 has a tight tolerance output voltage regulation of ± 0.5% (typ.) 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 protec tion to ensure maximum reliability.

Package options include the 3-pin SOT-23A and 3-pin SOT-89.
