Best Alternatives to TLV803SDBZR

Package: TO-236-3, SC-59, SOT-23-3Texas InstrumentsSupervisorsSeries: -Package: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Type: Simple Reset/Power-On ResetNumber of Voltages Monitored: 1Voltage - Threshold: 2.93V

TLV803SDBZR is a 3-pin voltage supervisor from Texas Instruments with a 2.93V threshold and 200ms delay. Finding a replacement requires matching these key parameters, along with the SOT-23-3 package and open-drain output.

AI replacement insight

Electrical risklow

Key parameters match, but max VCC is slightly lower.

Package risklow

Package is identical, but pinout requires verification.

Firmware risklow

No firmware interaction is expected for this type of component.

Can it be replaced directly?

Direct replacement for TLV803SDBZR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

TPV803S-3STR from 3PEAK is a strong candidate, matching key electrical parameters. Review the slightly lower max voltage.

Main risk

The primary risk is an incompatible pinout or an application VCC exceeding the candidate's 5.5V maximum rating.
