Product details

Shunt reference with a ±1% tolerance — what it buys you

The TLV431AILPR is a low-voltage adjustable shunt reference from Texas Instruments, the low-voltage sibling of the classic TL431. Its ±1% tolerance sets the worst-case output deviation at 25 °C — for a 2.5 V setpoint that is ±25 mV, tight enough for most comparator thresholds and regulator feedback dividers without trimming.

Output range and cathode current — where it fits

Output is adjustable from a minimum of 1.24 V up to 6 V, set by two external resistors. The 80 µA minimum cathode current lets you bias the reference with a high-value resistor, keeping quiescent draw low in battery-powered circuits.

Housed in a TO-92-3 through-hole package with formed leads, it is a direct drop-in for legacy board layouts that avoid SMT.

Frequently asked questions

What is the TLV431AILPR voltage reference accuracy and output voltage range?

Design engineers need to verify if the 1% tolerance and adjustable range meet their circuit requirements.

Where can I buy TLV431AILPR in stock and what is the current price?

Sourcing buyers need immediate availability and price to fill BOM lines without delays.

Is TLV431AILPR a direct replacement for TL431?

Maintenance techs and buyers often need drop-in alternatives for legacy designs.

What is the pinout and package type of TLV431AILPR?

Design engineers must confirm footprint compatibility for PCB layout and assembly.

Is TLV431AILPR active or obsolete?

Brokers and buyers need lifecycle status to ensure long-term supply and avoid redesign.

What is the TLV431AILPR cathode current range and minimum operating voltage?

Engineers must check if the part operates within their supply constraints.
