±0.5% shunt reference in SOT-89-3
The Texas Instruments TL432BIPK is an adjustable shunt voltage reference with a ±0.5% tolerance, packaged in a SOT-89-3 surface-mount case. It provides a 2.495 V minimum output, adjustable up to 36 V via two external resistors. This is the precision-grade variant of the TL432 family, suited for regulated supplies in industrial control, power management, and bias circuits where tighter set-point accuracy matters than the standard 1% or 2% grades.
100 mA sink, 700 µA cathode floor
The shunt can sink up to 100 mA of output current, which covers most local reference loads — ADC references, comparator thresholds, and low-drop biasing — without an external buffer. In a low-power design, verify the bias resistor sets the cathode current above this floor across the full input voltage range.
