LDO dropout question
« on: September 18, 2024, 02:26:38 am »
Hello, I would like to use the MIC61300 LDO to generate 2.5V and 3.0V power rails from a 3.3V power supply. I expect current draw of 100 mA on the 2.5 V rail and about 250mA on the 3.0 V rail. Would the MIC61300 be an appropriate choice for my requirements or should I pick another LDO? Would the 3.0V rail be problem if considering the 350mV max dropout voltage spec and it would enter dropout region? Any help is appreciated.

Looks like it'll be OK at 250mA:

3V rail, I would drop it at Schottky forward voltage.
