Product details

Adjustable shunt regulator, 1.24V to 6V output

Its ±1.5% tolerance holds the output tight enough for precision bias supplies, voltage monitoring, and secondary-side regulation in isolated converters. The 80 µA cathode current keeps the quiescent draw low in battery-powered or always-on circuits.

Industrial temperature grade and through-hole package

The TO-92-3 through-hole package (TO-226-3 / TO-92-3) is hand-solderable and breadboard-friendly — a practical choice for low-volume builds, prototyping, and rework where a surface-mount part would need a stencil or hot-air station.

Active lifecycle — no obsolescence clock

Frequently asked questions

Can TLV431ILP replace TL431?

The TLV431ILP is a lower-voltage sibling of the TL431 family — it operates down to 1.24V reference versus the TL431's 2.5V. In a circuit designed for a 2.5V reference, the TLV431ILP cannot directly substitute without changing the resistor divider. For a 1.24V reference application, it is a functional alternative, but always confirm the pinout and compensation stability with the specific load conditions.
