IC1 LM317LZ 200mA, TO-92 ($0.59) – This is the smallest common LM317 voltage regulator. The part linked can supply 200mA, but 100mA is more common.

Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a ...
