Part Number: TPS7A26
Other Parts Discussed in Thread: TPS7A11, TPS7A02

Hello LDO team.
Split from original thread: https://e2e.ti.com/support/power-management/f/196/t/883196

Please provide some suggestions Low Dropout Regulator selection, low Iq since battery power.

At the moment I develop a new product and need some help with the power components to find the best solution.

Hi Ed,

Ideally something like TPS7A02 would work great here for 200mA peak. Since peak current can be up to 500mA, I would like to suggest TPS7A11 if you have a bias rail that you can use in your application, otherwise TPS7A26 would be the device to use.

regards,

Wilson

Hi Wilson,

thanks for your suggestions. I haven't got a Bias-Rail, but I think the other two devices should work fine.

Best regards Jens Herrgesell
