Key Features
- Ultra-low 178mV typical dropout voltage enables efficient operation even with marginally higher input supplies
- Fixed 5.0V output with up to 250mA current delivery suits microcontroller and peripheral power rails
- Through-hole TO-92 package simplifies prototyping, hobbyist projects, and low-volume production builds
- Very low quiescent current minimizes standby power loss in battery-backed and sleep-mode designs
Applications
The MCP1700-5002E/TO is commonly used to provide a stable 5V regulated supply to microcontrollers, sensors, and logic circuits in prototyping boards, Arduino-based projects, and low-cost consumer electronics. Its very low dropout voltage makes it efficient when powered from a single lithium-ion cell or a lightly loaded 6V supply. The through-hole TO-92 package is also popular for educational kits and fieldservice repair of legacy industrial equipment.

Frequently Asked Questions
What is the output voltage and maximum current of the MCP1700-5002E/TO?
The MCP1700-5002E/TO provides a fixed 5.0V regulated output with a maximum output current of 250mA. The typical dropout voltage is 178mV, so the input supply must be at least 5.178V to maintain regulation under full load conditions.
What is the input voltage range for the MCP1700-5002E/TO?
The device operates with input voltages from the minimum needed to maintain regulation up to a maximum of 6V, with an absolute maximum rating of 6.5V. This range is compatible with alkaline battery packs, wall adapters, and low-voltage bench supplies commonly used in hobby and educational settings.
Does the MCP1700-5002E/TO require external capacitors?
Yes, the MCP1700-5002E/TO requires small bypass capacitors on the input and output pins for stable operation. Typically, a 1µF ceramic capacitor on the input and a 1µF ceramic or tantalum capacitor on the output are recommended to ensure loop stability and reduce output noise across the full load range.
What package is the MCP1700-5002E/TO available in?
The MCP1700-5002E/TO is housed in a 3-pin TO-92 through-hole package, the same footprint used by many discrete transistors. This familiar package is easy to solder by hand, making it popular for DIY electronics projects, educational kits, and prototyping applications.
Can the MCP1700-5002E/TO replace a 7805 regulator?
In low-current applications the MCP1700-5002E/TO can substitute for a 7805 voltage regulator since both provide 5V output in a TO-92/TO-220 package, but the MCP1700 is limited to 250mA versus the 7805's 1A. The MCP1700 offers a significantly lower dropout voltage (178mV vs. 2V for a 7805), making it more efficient in battery-powered designs where input headroom is limited.
