Applications
The MCP1701AT-5002I/CB is optimized for battery-powered IoT nodes, portable instruments, and wireless sensor modules that demand a 5.0 V rail with minimal standby current drain. Its 2 µA quiescent current makes it one of the lowest-power options in the Microchip LDO portfolio, extending shelf life and battery runtime in always-on applications. The SOT-23A-3 package minimizes PCB area, and the 250 mA output is sufficient for powering microcontrollers, sensors, and small RF modules.

Frequently Asked Questions
How does the MCP1701AT-5002I/CB achieve such a low quiescent current and why is that critical for IoT designs?
The MCP1701AT-5002I/CB draws only 2 µA of quiescent current regardless of load, which in a coin-cell or AA-battery-powered IoT sensor can extend battery life by months compared to regulators consuming 50 µA to 100 µA at idle. For a device sleeping most of the time at 5.0 V, the regulator itself contributes negligibly to total energy drain.
What is the dropout voltage of the MCP1701AT-5002I/CB and what minimum input voltage is required to maintain 5.0 V output?
The MCP1701AT-5002I/CB has a typical dropout voltage of 0.38 V and a maximum of 0.6 V at full 250 mA load, meaning the input voltage must be at least 5.6 V to guarantee a regulated 5.0 V output. The specified input range starts at 6 V, providing a comfortable margin for 9 V battery supplies as they discharge toward end-of-life.
Can the MCP1701AT-5002I/CB power a microcontroller and wireless module simultaneously from a single 9 V battery?
Yes, the MCP1701AT-5002I/CB can deliver up to 250 mA at 5.0 V from a 9 V battery, which is sufficient to power a PIC or AVR microcontroller drawing under 30 mA and a low-power wireless module drawing under 100 mA, with margin remaining for other loads. The SOT-23A-3 package occupies minimal board space, making it practical for compact single-supply designs.
