TL431AIDBZR 3D Model
TL431AIDBZR is an adjustable precision shunt regulator, belonging to the three-terminal shunt regulator family with an output voltage range between Vref and 36 V, to be set by two external resistors.
• The TL431xDBZR types feature an enhanced stability area with a very low load capacity requirement.
• The TL431xFDT types offer an enhanced stability area and a higher ElectroMagnetic Interference (EMI) ruggedness, for example, for Switch Mode Power Supply (SMPS) applications.
• The TL431xSDT types are designed for standard requirements and linear applications.
Programmable output voltage up to 36 V
Three different reference voltage tolerances:
Standard grade: 2 %
A-Grade: 1 %
B-Grade: 0.5 %
