3.0V regulator?

[technix]

I am going to ditch the AXP203 PMIC for Allwinner V3s in my DIY camera design and opt for a few SOT23-5 regulators and a STM32F030F4P6 as the platform controller IC. The AXP203 is a nightmare to wire up and I am not comfortable soldering QFN with an iron. Now I am trying to find the LP2980-3.0 for the 3.0V VDDANA rail (2.8-3.3V limits, 3.0V typical). However so far, no luck. Nobody I know of is selling those. Is there any alternative solutions?

How to generate the 3.0V rail without the LP2980-3.0 then? On the board there are LM3671-3.3 switch-mode regulators already there for the I/O rails, can I drop it with a SS14 Schottky rectifier or BAT54A dual Schottly diode, put a LC filter after that and call it a day?

or a mic550x?

You could use an adjustable regulator and calculate the resistor values for 3.0V, it only takes two resistors and you have a fixed regulator of whatever voltage you want.
