Lp5907 Iq and Ig estimates with Vin, Ven = 3.3V and Iout =1mA

Jay Jang

I’m trying to do the quiescent current roll-up and was wondering if you have numbers under different test conditions that you could guarantee?

VEN=3.3V, VIN=3.3V, IOUT=1mA

What would be the IQ and IG figures under this arrangement?

Thanks

"... if you have numbers under different test conditions that you could guarantee? ..."

The only ensured values are what's listed in the datasheet.

Do we have some test data for the customer at the settings outlined? Even if it is not guaranteed

I don't have any data for the settings outlined.

I can bench test one or two parts, I need to know the Vout first

Vin= 3.3V

Ven= Vin

Iout=1mA

Vout = ??

1.8 and 2.8 Vout

Thanks!
