As a shunt-type reference, the TL432IPKG3 regulates by shunting current away from the load; the 1 mA minimum cathode current must be drawn continuously, which sets a floor on the bias resistor power dissipation in the design. ## SOT-89-3 package and surface-mount layout Housed in a TO-243AA package, also designated SOT-89-3, this surface-mount device occupies a compact footprint suitable for dense PCB layouts in power supplies, battery chargers, and instrumentation. The three-pin configuration (cathode, anode, reference) is identical to the industry-standard TL431 pinout, allowing drop-in replacement in existing TL431-based designs with attention to the tighter tolerance grade.","metaTitle":"TL432IPKG3 Shunt Voltage Reference, Adjustable 2.495V to 36V","metaDescription":"TL432IPKG3 adjustable shunt voltage reference from Texas Instruments.
