TPS7A14: I-Bias Spec

Hey McKenna,

I'm looking into your question, please allow at least 2 business days for an answer.

Thanks

Hi Vahnroy,

Following up on this.

Thanks!

Hey.

For the DRV package Ibias max is approximately 41.7 and for ybk 25.3

Hope this helps,

Vahnroy

Hi Vahnroy,

Thanks for helping gather this information for me. I'm more so asking about the specific use case value. Assuming following numbers are in uA, 41.7uA is the max bias current for 1.2V @50mA use case ?

Just wanted to highlight the question again, please let me know if you need any clarification.

“

I have quick question regarding TPS7A14. I see I-Bias current spec from datasheet for 1A IOUT, do you have details of what this current will be for Iout of 50mA ?

I’m mainly trying to assess if this makes more sense to go with ultra drop out with bias current penalties or use regular ~150mV part like TPS7A2018 for 1.2V @50mA application that need higher PSRR.

Thank you!

McKenna

Hey Mckenna,

Yes, those values were for the specific use case. Do those values align with your application needs?

Thanks,

Vahnroy
