MCP101-300DI/TO Microchip Integrated Circuit (Other) In Stock
The MCP101-300DI/TO is a single-channel voltage supervisor and microprocessor reset IC from Microchip with a fixed 3.0 V trip threshold. It asserts an active-low RESET signal when the monitored supply drops below the threshold and is housed in a 3-pin TO-92 through-hole package, providing straightforward brownout protection for embedded systems and legacy designs.

Applications
The MCP101-300DI/TO is primarily used to generate a reliable power-on and brownout reset signal for microcontrollers, FPGAs, and DSPs running on a 3.0 V or 3.3 V rail. Its TO-92 package is favored in prototype boards, repair replacements, and legacy industrial designs where SMD alternatives are not practical.

Frequently Asked Questions
At what supply voltage does the MCP101-300DI/TO assert its RESET output?
The MCP101-300DI/TO asserts its active-low RESET output when the monitored supply falls below the fixed 3.0 V threshold. It holds RESET asserted for a specified delay period after the supply recovers above the threshold, preventing false MCU starts during slow power-rail ramp-up scenarios.
Can the MCP101-300DI/TO be used on a 3.3 V rail, or is it strictly for 3.0 V supplies?
The MCP101-300DI/TO is rated to monitor supplies in the range up to 5.5 V, and its 3.0 V trip threshold makes it a common choice on 3.3 V rails where a low-side undervoltage margin of roughly 300 mV is acceptable. If a tighter threshold is needed, the MCP101 family offers additional threshold options from 2.3 V to 4.5 V.
How does the TO-92 package of the MCP101-300DI/TO compare to SOT-23 voltage supervisors for production PCBs?
The 3-pin TO-92 through-hole package requires drilled holes and hand or wave soldering, making it less suitable for high-volume SMT production lines compared to SOT-23 or SC-70 alternatives. However, it is advantageous in prototyping, field repair, and legacy boards that already use through-hole components or lack SMT reflow capability.
What is the factory lead time for the MCP101-300DI/TO, and should buyers plan safety stock?
The MCP101-300DI/TO has a factory lead time of 21 weeks, which is longer than typical for simple analog supervisors. Buyers sourcing for production runs should maintain at least 6 months of safety stock or qualify a second source to avoid supply chain disruptions, especially given the YTEOL of 8 years.
