Hi Koyo-san,

I would have to submit a request to take this data. Can you comment on why the customer is interested in this particular IC?

We have newer LDO's,

Hi JCHK,

Thanks, please let me know when you get the data.

Customer had looked for fixed output with 1.5A, so there were limited options.
But adjustable LDO can be accepted.
If you can suggest, please recommend better device than LP3892.

Best regards,
Koyo

Hi Koyo-san,

This looks like it could take up to a week or two.
