Adafruit P2166 identifies the ST 3.3 V TO-92 version. Up to 250 mA is subject to input-output differential and package thermal dissipation; not a guaranteed continuous current in every circuit. Approximate 0.4 V dropout is not a guaranteed maximum. Datasheet 20 V input is an absolute maximum, not a recommended operating limit, so no supply maximum assigned. Exact C/AB tolerance grade is not read from the chip.
Description
Fixed positive low-dropout regulator for small 3.3 V power circuits, with internal current limiting and thermal shutdown. Three-pin TO-92 variant has no inhibit pin. Observe datasheet pin orientation and capacitor requirements; Adafruit recommends at least 2.2 µF electrolytic capacitors at input and output. Product: https://www.adafruit.com/product/2166
