What are the key features of MCP120T-270I/TT?
- Fixed 2.70 V reset threshold with single-channel voltage supervisor in a minimal SOT-23-3 3-pin package
- Manual reset output without watchdog timer keeps silicon area and BOM cost minimal for simple reset applications
- Supports industrial temperature range operation in a compact surface-mount package for space-constrained designs
What is MCP120T-270I/TT used for?
The MCP120T-270I/TT is designed to assert a processor reset whenever the supply voltage drops below the 2.70 V threshold, ensuring clean microcontroller startup and brownout protection in embedded systems. It is commonly placed near 3.3 V or 2.7 V powered microcontrollers in IoT sensors, portable medical devices, and battery-operated instruments. The SOT-23-3 footprint occupies minimal PCB area, making it ideal for compact single-board computers and module designs.

Frequently Asked Questions
At what supply voltage does the MCP120T-270I/TT assert a reset, and for how long?
The MCP120T-270I/TT asserts reset whenever the monitored supply falls below its fixed 2.70 V threshold. It holds reset active until the supply recovers above the threshold without a programmable delay, providing a simple and reliable brownout detection mechanism for 3.3 V or 2.7 V microcontroller systems.
Does the MCP120T-270I/TT include a watchdog timer or programmable reset delay?
No, the MCP120T-270I/TT does not include a watchdog timer, programmable reset delay, or power-fail output. It provides only a single manual reset output, which minimises quiescent current and keeps the SOT-23-3 pin count to 3 pins for the simplest possible supervisor implementation.
Which microcontroller families and supply rails is the MCP120T-270I/TT best suited to supervise?
It best supervises microcontrollers running from 2.7 V to 3.3 V rails, such as PIC and AVR devices at 3.3 V or low-power ARM Cortex-M0 parts at 2.7 V. Its fixed 2.70 V trip point ensures reset is released with at least 0 mV of headroom above the typical minimum operating voltage of 2.7 V devices.
