The 700 µA minimum cathode current sets the minimum bias the shunt needs to maintain regulation — below that the device drops out. Designers targeting low standby power should size the bias resistor to keep the cathode current above 700 µA across the full input voltage range. The SOT-89-3 package (TO-243AA) with a large collector tab helps dissipate heat in high-ambient conditions. Designers can specify this part for new BOMs without supply-chain urgency. ## ±1% tolerance — precision where it matters The reference voltage tolerance is ±1%.","metaTitle":"TL432AQPK Shunt Regulator, Adjustable, 2.495V Ref, ±1%","metaDescription":"TL432AQPK adjustable shunt voltage reference, 2.495V min output, 100 mA output, ±1% tolerance, -40°C to 125°C, SOT-89-3.
