Product details

Active-production shunt reference in SOT-23-3

The TL432AQDBZTG4 is a Texas Instruments adjustable shunt voltage reference with a 2.495 V fixed minimum output, ±1% tolerance, and 100 mA output current capability.

Parametric fit: tolerance, output, and cathode current

The ±1% tolerance on the 2.495 V reference voltage suits precision power-supply feedback loops and voltage monitoring circuits where better than 2% accuracy is needed. The 100 mA output current handles moderate loads in shunt regulator and series-pass configurations. Minimum cathode current is 700 µA, which sets the bias floor for stable regulation — below this the device may not regulate properly.

Frequently asked questions

Is TL432AQDBZTG4 equivalent to TL431?

The TL432 is functionally similar to the TL431 but uses a different pinout — the reference and cathode pins are swapped. They are not pin-compatible; verify the PCB footprint before substituting.
