Applications
The MCP111T-195I/LB is used in microcontroller reset circuits, battery-powered handheld devices, and portable consumer electronics that require a reliable low-voltage supervisory function. It monitors supply rails and asserts an open-drain reset signal when the voltage drops below the 1.95 V threshold, preventing erroneous code execution. Its tiny form factor suits wearable devices, IoT sensor nodes, and any design demanding minimal board area.

Frequently Asked Questions
What is the reset threshold voltage of the MCP111T-195I/LB and how accurately is it maintained over temperature?
The MCP111T-195I/LB has a fixed reset threshold of 1.95 V. The threshold accuracy is typically within ±2%, meaning the actual trip point stays between approximately 1.91 V and 1.99 V across the full -40°C to +125°C industrial temperature range, making it reliable for low-voltage 2 V rail supervision.
Which battery-powered applications are best served by the MCP111T-195I/LB versus a higher-threshold supervisor like MCP111T-270?
The MCP111T-195I/LB at 1.95 V threshold is ideal for single-cell lithium systems running a 1.8 V or 2.0 V core, whereas the MCP111T-270 at 2.70 V suits alkaline or NiMH packs. If your regulated rail is 2 V or below, MCP111T-195I/LB provides the right margin with open-drain output drive and quiescent current under 20 µA, extending battery life by months in IoT sensor nodes.
How much board space does the SOT-23-3 (SC70-3) package of MCP111T-195I/LB require, and what is the pin count?
The MCP111T-195I/LB ships in a 3-pin SOT-23 package measuring approximately 1.3 mm × 2.9 mm, occupying roughly 3.8 mm² of board area. Its 3 pins (VDD, GND, and RESET output) simplify layout to a two-capacitor decoupling circuit, making it one of the smallest footprint voltage supervisors available for high-density PCBs.
