Product details

Adjustable shunt reference — ±1% tolerance in a TO-92-3

It provides a precision 1.24 V minimum output with ±1% tolerance, adjustable up to 6 V via an external resistor divider. The 15 mA output current and 80 µA cathode current suit it for feedback loops in power supplies, battery chargers, and general-purpose voltage monitoring where a low-cost, accurate reference is needed.

The TLV431ACLPRE3 is listed as obsolete. For new designs, consider the active TLV431 series variants in SOT-23 or SOT-89 packages.

Key ratings for BOM fit

The ±1% tolerance is the headline spec for precision feedback — it sets the output voltage accuracy without external trimming. The 15 mA output current defines the maximum load the shunt can sink while maintaining regulation; derate for temperature rise in the TO-92-3 package.

Frequently asked questions

Is TLV431ACLPRE3 compatible with TL431?

The TLV431 is a low-voltage variant of the TL431, with a 1.24 V reference instead of 2.5 V. They are not pin-compatible for direct replacement without adjusting the feedback resistor divider. The TLV431ACLPRE3 uses the same TO-92-3 pinout as the TL431, but the reference voltage difference changes the output equation.
