LP2985A: Efficiency Curve

Part Number: LP2985A

Dear Team,

Do we have efficiency curve for LP2985A-33DBVR?



  • Hi Kevin,

    To the first order for any Linear Regulator, the efficiency is simply VOUT/VIN.

    For the actual efficiency, it is VOUT*ILOAD/VIN(ILOAD+IQ(LOAD)).

    Where IQ(LOAD) is the IQ at the given load current. 

    Does this answer your question?
