The reset output is Active Low and push-pull (totem pole), so it drives the reset pin of most MCUs and SoCs directly without an external pull-up resistor. The SC-70-3 package fits tight layouts where board area is the constraint. The 2.63V threshold is a common choice for 3.3V logic rails — it trips before the supply falls below the minimum operating voltage of most 3.3V processors. The SC-70-3 package is widely stocked across the supply chain.","metaTitle":"MCP102T-270E/LB Simple Reset/Power-On Reset, 2.63V Threshold","metaDescription":"Microchip MCP102T-270E/LB supervisor IC: Active Low reset, 2.63V threshold, 80ms timeout, -40°C to 125°C, SC-70-3.
