LM78L: Short circuit output current

Part Number: LM78L

Hello Guys,

Good day.

What is the short circuit output current for this device?

Thanks!

  • Hi Art,

    The short-circuit current limit is not listed in the datasheet, unfortunately, so there is not much we can do to know the designed-in limit. We do know that LM78L has built-in thermal protection, so we can estimate how much current the LDO will allow based on this in the event of a short-circuit event if the input voltage and ambient temperature is known using Figure 1.

    Best regards,

    Nick
