nPM1300 LDO quiescent current

[lewisleman]

Hello,

I'm evaluating the nPM1300 for a battery powered project. What is the quiescent current of the LDO? And is there an output current vs dropout chart?

Thanks

Hi lewisleman,

The quiescent current for Ship and Discharge mode are provided in section 3.7, Electrical characteristics, of the product specification. Typical value is also noted in the next section, System electrical specifications.

There doesn't seem to be an output current vs dropout chart yet, unfortunately.

The description doesn't mention LDO operation. I assumed the LDO is disabled for this condition. Can you confirm if the test condition for the 800nA spec includes LDO turned on?

My apology. LDO quiescent current is 4.5uA from the VSYS rail and 8uA from the LSINx.

This is the dropout vs output current chart:

This is perfect. Thank you

I'm glad it helped. Please feel free to close this case at your convenience then.
