Frequently Asked Questions

What is the output voltage range of the TL431AIDCKR?

The TL431AIDCKR provides an adjustable output voltage range from 2.495V (internal reference voltage) up to 36V, with 1% initial accuracy. The output voltage is set by an external resistor divider connected to the reference (REF) pin.

What package does the TL431AIDCKR use and what are its dimensions?

The TL431AIDCKR is housed in a 6-pin SC-70 (DCK) small outline package. This compact surface-mount package is ideal for space-constrained PCB designs and is RoHS compliant (Pb-free, JEDEC e3 rated).

What are typical applications for the TL431AIDCKR?

The TL431AIDCKR is commonly used in switching power supply regulation, optocoupler-based feedback loops, voltage monitoring circuits, battery chargers, and precision reference voltage generation. Its adjustable 2.495–36V range and 100mA sink capability make it versatile across industrial and consumer designs.

Is the TL431AIDCKR compatible with standard TL431 circuits?

Yes, the TL431AIDCKR is pin-compatible and functionally equivalent to other TL431 variants. It can be used as a drop-in replacement in existing TL431-based designs, provided the SC-70 footprint is used on the PCB.
