Hmm. Doesn't work quite as I had in mind.

Quote:

ENABLE input. The device turns off, the output disconnects from the input, and the supply current decreases to
0.05 µA when ENABLE is a logic low. ENABLE High may only be applied when VIN is inside the recommended
operating range.

Not quite. When ENABLE is held logic low, it puts out 0.8v and draws about 1.7mA driving the device. When ENABLE is held logic high, it puts out its 3.3v as expected.

As I vary the supply voltage throughout the specified range, the output holds a nice steady 3.3v as intended, all the way from 1.8 to 3.6 volts.

I'll examine it more in the morning. Today's project was to construct the board.

(The connector to the TFT display is on the bottom. That's where most of those processor pins go.)

Yes. R8 is upside down and crooked. It comes out the right resistance, so I'm not going to worry about it. I also forgot to ground the ground pin of the ISP connector, and connected the input to the 3v regulator to the wrong supply. Two green wires so far. Not too bad. Yet.
