Product details

2.93V threshold supervisor for 3.3V rails

The TPS3801K33DCKRG4: The active-low, push-pull output asserts reset immediately when VDD falls below 2.93V and holds it low for a minimum of 120ms after the supply recovers, giving the processor time to stabilise before release.

SC-70-5 footprint and industrial temperature range

Housed in a 5-pin SC-70-5 (SOT-353) package, this supervisor fits tight PCB layouts where board area is at a premium — the 0.65mm pitch and 2.0mm × 2.1mm body consume less than 5mm².

The base product number TPS3801 spans multiple threshold options and package variants.

Frequently asked questions

Can TPS3801K33DCKRG4 replace TPS3801K33DCKR?

The TPS3801K33DCKRG4 is functionally identical to the TPS3801K33DCKR — same threshold, same timeout, same package. The 'G4' suffix indicates a lead-free (RoHS) plating finish. If your BOM calls for the non-G4 variant, this part is a drop-in replacement as long as your assembly process accepts the lead-free finish.
