Product details

Adjustable shunt reference — ±0.5% tolerance in SOT-23-3

The B-grade bin locks initial tolerance to ±0.5%.

Output current and cathode bias — driving the feedback network

The device is rated for 15 mA continuous output current and requires a minimum cathode current of 100 µA to maintain regulation. The adjustable output range runs from 1.24 V up to 6 V.

Frequently asked questions

Does TLV431BQDBZRG4 have a fixed output voltage?

No, the output type is adjustable. The minimum fixed output is 1.24 V, and the maximum output is 6 V, set by an external resistor divider. This is the same adjustable topology as the TL431 but with a lower minimum operating voltage.
