LM70840-Q1: Efficiency LM708X0-Q1 at light loads: around 70uA 5V output

Hi! Happy new year!

We have a question about the LM708x0 about the efficiency at light loads. In the datasheet it is specified from 1mA @5V output.

Could you provide the efficiency for 70uA load (at 5V output), for 12V and 24V Vin? From simulations we have around 70uA load current at 5V.

Thank you in advance

Hi Alex,

Please be patient as we are getting the data for you.

Hi Alex,

Here is the data I was able to obtain:

Note that the 86uA load is closest to 70uA that the equipment (e-Load) has allowed me to apply.

Best regards,
Davor
