Product Summary

The TL431BID is a programmable shunt regulator diode. The voltage references of the TL431BID operate as a low temperature coefficient zener which is programmable from Vref to 36V with two external resistors. The TL431BID exhibits a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω.
