TL431: output current

Part Number: TL431
Other Parts Discussed in Thread: TLVH431, ,

Tool/software:

Hi team,

I noticed the rated output current is 70mA in TLVH431BQDBZR, do we have the device with 100mA or higher rated output current?

and Could you provide the temperature derating curve with customer?

    Hi Jingguo,

    For a shunt reference, the output current is determined by the resistors used for the input, load, and divider. However if you are looking for a larger cathode current, for a 1.24V reference, TLVH431 provides the highest cathode current. If you would be willing to use a 2.5V reference, you could consider TL431 or ATL431, which both have higher cathode current capability. 

    Here is the reference voltage vs temperature plot from the TLVH431 datasheet:

    Thanks,

    Jackson
