Product details

Adjustable shunt reference in a small SOT-23-3 footprint

It delivers a 2.5 V minimum output, adjustable up to 24 V, with a ±0.5% tolerance and a 100 mA output current capability. The 1 mA cathode current keeps the quiescent draw low, making it a fit for precision bias supplies, error amplifiers, and monitoring circuits in industrial control, power supplies, and automotive electronics.

The SOT-23-3 footprint matches the industry-standard SC-59 / TO-236-3 land pattern, so no board respin is needed when swapping between similar shunt references.

It is ROHS3 compliant, meeting current EU material restrictions. No last-time-buy or obsolescence risk for new designs.

Frequently asked questions

Can TS2431BILT replace the TL431 in my design?

The TS2431BILT is a functional equivalent to the TL431 family — both are adjustable shunt references with similar pinout and operating principles. Verify the specific tolerance (±0.5% vs typical TL431 ±1%) and temperature range (-40°C to 105°C vs typical 0°C to 70°C) against your design requirements before substitution.
