Product details

The TPS3839L30DBZT: ROHS3 compliant.

2.63V threshold — matching the 3.3V rail dropout point

The voltage threshold is 2.63V, which sits at roughly 80% of a nominal 3.3V supply. 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.

Frequently asked questions

Is TPS3839L30DBZT active low reset?

Yes, the reset output is active low with a push-pull (totem pole) stage. It drives the MCU reset pin directly without an external pull-up.

What is the reset timeout for TPS3839L30DBZT?

The reset timeout is 120ms minimum, giving the supply rail time to settle before the processor starts executing code.

What package does TPS3839L30DBZT come in?

It comes in a SOT-23-3 package (also listed as TO-236-3, SC-59). The supplier device package is SOT-23-3.
