LM380: Quiescent Supply Current

Part Number: LM380


My customer would like to know minimum Quiescent Supply Current because they use its spec as criteria of  good unit or bad unit.

I know there is no Min spec of Quiescent Supply Current on our data sheet.

Do we have any referential data or estimated value ?

Any advice will be appreciated.


  • Hi Jin,

    Unfortuantely we don't have any further data than what is included in the data sheet. Specially for these old legacy devices.
    Perhaps you can also inspect bypass pin voltage.
