Nicholas I. ★★★★★

Been feeding this module with 9V from a wall wart and it’s been holding steady at 3.3V for a week now. The 4.75V to 12V input range made it super easy to fit into my existing project without extra parts.

Robert ★★★★★

This little chip handles my 4.75V battery input down to a steady 3.3V without any flickering, and the AMS1117 regulator feels solid for such a tiny part.

Harper K. ★★★★★

Was hesitant because I've had cheap regulators drift before, but this one holds 3.3V rock steady even when I feed it 9V from an old wall wart. The 4.75-12V input range gave me plenty of headroom to work with.
