Product details

What this supervisor does for your power rail

The push-pull output drives the reset line without an external pull-up resistor, saving a component on the board. That 5µs window matters when the rail droops under a sudden load step.

The SC-70-5 package occupies minimal PCB area — about 2.0 mm × 2.1 mm — and the 0.65 mm pitch is routable on a two-layer board. The SC-70-5 footprint is shared with many simple reset ICs, so a board swap to a different supervisor is straightforward if the threshold or timeout needs to change.

ROHS3 compliant. Sourced per RFQ — confirm current pricing and lead time against your order quantity. No stock-holding claim; availability confirmed at quote time.

Frequently asked questions

What package does TPS3805H33MDCKREP come in?

It is supplied in an SC-70-5 package, also referred to as SOT-353. The supplier device package is SC-70-5.

Is TPS3805H33MDCKREP compatible with 5V systems?

The 3.05V threshold is designed for monitoring a 3.3V rail, not a 5V rail. For a 5V system, select a supervisor with a threshold near 4.6V or use the adjustable version of the TPS3805 family with the appropriate resistor divider.
