Part Number: TL432LI

My client wants to use TL432LI for LA431, IKA parameters are as follows, will there be any side effects?

TL432LI IKA:  1mA~15mA

LA431 IKA: 0.3mA~100mA

  • Hi Hsu,

    I cannot comment on side affects without knowing the application and schematic. In most situations the TL431LI can be a drop in replacement but if they require lower Ika then they can use a ATL431LI.

    Can you give us more information on the use case?

    Is this being used as a reference to an ADC or as optocoupler feedback in PD?

    If you are using the TL431, check out the new ATL431LI for improved system performance in a p2p package or a ultra  small X2SON (1mm x 1mm x 0.4mm)
