For a typical 2.5 V reference pulling 10 mA to bias an optocoupler, that leaves 90 mA of headroom, but if you are also supplying a downstream load through the same shunt, budget the total. The 600 µA minimum cathode current is the floor below which the reference stops regulating. In a low-power standby supply running at 200 µA total, this part will not work — you need a lower-I(min) reference or a different topology.","metaTitle":"TL432ACDBZTG4 Texas Instruments Adjustable Shunt Reference","metaDescription":"TL432ACDBZTG4 adjustable shunt voltage reference from TI. ±1% tolerance, 100 mA output, 600 µA cathode current.

The key difference is the pinout: the TL432 in SOT-23-3 swaps the reference and anode pins relative to the TL431 in the same package, so a board laid out for a TL431 will not accept a TL432 without a PCB respin."},{"question":"How much current can TL432ACDBZTG4 sink?","answer":"It can sink up to 100 mA continuous cathode current while maintaining regulation.
