Product details

Adjustable shunt reference — 2.495 V to 36 V, ±1% tolerance

It delivers a 2.495 V reference at the cathode with a ±1% tolerance, and the output can be set anywhere from 2.495 V up to 36 V using two external resistors. The 100 mA output current capability and 700 µA minimum cathode current define the bias resistor range and the load it can drive in shunt configuration.

SOT-23-3 package — footprint and sourcing

The small footprint suits space-constrained designs in power supplies, battery chargers, and voltage monitoring circuits.

Frequently asked questions

What is the tolerance and accuracy of TL431AIDBZTG4?

The TL431AIDBZTG4 is specified with a ±1% tolerance on the reference voltage. This is the standard precision tier for the TL431A family, suitable for general-purpose regulation, monitoring, and feedback loops where better than ±2% is needed but sub-0.5% is not required.
