Product details

Adjustable shunt reference, ±1% bin, 8-SOIC

The TL431ACDRG4 is a three-terminal adjustable shunt regulator from the TL431 family, with a ±1% initial tolerance on the 2.495 V internal reference. The 100 mA output current capability and 600 µA minimum cathode current define the operating window for biasing optocouplers in isolated supplies or setting a precision voltage rail in a linear regulator.

Output voltage range and temperature grade

The adjustable output spans from the 2.495 V minimum up to 36 V maximum, set by two external resistors.

Frequently asked questions

What is the accuracy of TL431ACDRG4?

The initial tolerance is ±1% on the 2.495 V internal reference. This is the 'A' grade bin; the standard TL431 is ±2%.

What is the typical application of TL431ACDRG4?

It is used as a precision shunt voltage reference in linear and switch-mode power supplies, for biasing optocouplers in isolated feedback loops, and as a programmable reference in data converters or monitoring circuits.
