Product details

2.93V threshold — what it watches

The TPS3838K33DBVRG4 is a single-channel voltage supervisor from TI's TPS3838 family, a Simple Reset/Power-On Reset type. The open-drain output (active low) lets you pull up to any voltage up to the absolute maximum of the device.

SOT-23-5 footprint, surface-mount assembly

Housed in a 5-pin SOT-23-5 package, this supervisor takes minimal board area. The standard SOT-23-5 land pattern makes it a drop-in for many existing supervisor footprints.

The base product number TPS3838 covers multiple threshold options in the same SOT-23-5 footprint, so the broader family remains available for design flexibility.

Frequently asked questions

What is the reset timeout of TPS3838K33DBVRG4?

The reset timeout is a minimum of 10ms. After the supply rises above the threshold, the output remains low for at least 10ms to allow the system supply to stabilise before the processor starts.
