The AMS1117 datasheet provides specifications, electrical characteristics, package dimensions, and application notes for the 1 A low dropout voltage regulator.
The AMS1117 series are three‑terminal adjustable or fixed low‑dropout voltage regulators capable of delivering up to 1 A output current with a maximum dropout of 1.3 V. They are pin‑compatible with older three‑terminal regulators and are offered in SOT‑223, TO‑252 (DPAK) and 8‑lead SOIC packages.
This datasheet includes ordering information, pin connections, absolute maximum ratings, detailed electrical characteristics (output voltage, line and load regulation, ripple rejection, thermal data), application hints, thermal considerations, typical performance curves, and mechanical package dimensions.
