That means the reset asserts before the rail drops below the minimum operating voltage of most 3.3V-logic MCUs and DSPs, giving the processor a clean shutdown signal before the logic becomes unreliable. The reset output is active-low push-pull (totem pole), so it drives the reset pin directly without an external pull-up resistor. ## Industrial temperature grade and SOT-23-3 footprint The SOT-23-3 package (TO-236-3, SC-59 equivalent) is a three-pin footprint that fits tight layouts and is straightforward to hand-solder or reflow. It monitors a single voltage rail. Surface-mount assembly is standard.","metaTitle":"TPS3839L30DBZT – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3839L30DBZT supervisor IC: active-low reset, 120ms timeout, -40°C to 85°C, SOT-23-3.
