TPS7A20: Part substitution

Nandini Muralidharan
Intellectual 810 points
Part Number: TPS7A20

Tool/software:

Hi,

I want to replace TPS79918QDDCRQ1 with TPS7A2018PDBVR since I need a higher current rating.

I observe that the parts are very close. TPS7A2018 has lower voltage dropout but cheaper than the original part.

Is there any spec which is on lower side for TPS7A2018 that I should be aware of?

The application is automotive (temp: -40 to 125C) and current rating requirement is 250mA.

Thanks
