Adjustable shunt reference — what it does in the circuit
It provides a stable 2.495 V reference at the cathode when the adjust pin is tied to the cathode, and the output can be set anywhere from 2.495 V up to 36 V using two external resistors. Rated for 100 mA continuous output current with a minimum cathode current of 1 mA, it suits linear regulators, switching power supply feedback loops, and precision voltage monitoring in industrial and automotive environments.
Sourcing is limited to independent distribution and surplus inventory.
Package and temperature grade — fit for harsh environments
Housed in a SOT-23-5 surface-mount package, the TL432QDBVT shares the same footprint as many other adjustable shunt references, making it a candidate for drop-in replacement evaluation.
