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.","metaTitle":"TL432BIPK Adjustable Shunt Reference, ±0.5% Tolerance","metaDescription":"TL432BIPK adjustable shunt voltage reference. ±0.5% tolerance, 100 mA output, 700 µA cathode current.
