Product details

What the 2.941V threshold means for your 3.3V rail

The TPS3106K33DBVR is a single-channel voltage supervisor that asserts a reset when the monitored supply drops below 2.941V. On a nominal 3.3V rail, that threshold sits roughly 12% below the regulated voltage — early enough to catch a brownout before the downstream logic glitches, but not so tight that noise triggers false resets. That 65ms floor is the spec to check against your power-on reset timing budget.

Package and layout — SOT-23-6

The SOT-23-6 package is a 6-pin surface-mount footprint with 0.95mm pitch — routable on a 2-layer board without micro-vias. If your BOM requires a 125°C rating, the TLV803 family extends to that range.

Active production — no last-time-buy watch

ROHS3 compliant.

Frequently asked questions

What is the reset timeout of TPS3106K33DBVR?

The reset timeout is 65ms minimum. After the supply rises above the threshold, the reset output stays low for at least 65ms before releasing.

Is TPS3106K33DBVR compatible with 3.3V systems?

Yes — the 2.941V threshold is designed for nominal 3.3V rails. The supervisor monitors the supply and asserts reset before the rail drops below the logic's minimum operating voltage.

What is the TPS3106K33DBVR equivalent or alternative?

The TLV803EA29VDBZR and TLV803ED29DBZR are functional peers with the same active-low open-drain output and SOT-23-6 package. Key differences: the TLV803 variants offer a 1.0V supply voltage minimum and extended temperature range to 125°C, while the TPS3106K33DBVR is specified at -40°C to 85°C. The TLV803EA29VDBZR has a 130ms reset timeout; the TLV803ED29DBZR has a 33ms timeout.
