Frequently Asked Questions

What is the threshold voltage range of the MCP112T-270E/LB, and how tight is the tolerance?

The MCP112T-270E/LB has a threshold window of 2.564 V to 2.696 V, giving a nominal 2.63 V trip point with roughly ±2.5% tolerance. This precise window ensures reliable brownout detection on 2.5 V or 3.3 V regulated supplies without false resets under normal load transients.

For a wearable device using a 2.5 V LDO, would the MCP112T-270E/LB provide adequate undervoltage protection?

Yes. The MCP112T-270E/LB is specifically rated for a 2.564 V to 2.696 V reset threshold, which sits just below a 2.5 V regulated rail. When the supply dips below the threshold, the device asserts its active-low RESET output, protecting the MCU from operating with insufficient voltage.

How does the SC-70 package of the MCP112T-270E/LB affect PCB layout compared to SOT-23 voltage supervisors?

The 3-pin SC-70 package has a body size of approximately 2.0 mm × 1.25 mm — noticeably smaller than the standard SOT-23 body — allowing designers to place the voltage supervisor closer to the MCU VDD pin and reduce total solution area by 30–40% on compact boards.

Is the MCP112T-270E/LB compliant with RoHS and halogen-free requirements for consumer electronics certification?

Yes, the MCP112T-270E/LB carries a Pb-free (lead-free) designation and is RoHS compliant, with a JESD-609 e3 code indicating MSL 3 moisture sensitivity. This makes it suitable for standard reflow soldering processes used in consumer, industrial, and medical electronics production.
