The AMS1117-3.3 is a linear voltage regulator with a SOT-223-3L package. It is designed to provide a low-noise, low-dropout voltage regulation for up to 3A of output current. This regulator is RoHS compliant and is manufactured by the Taiwan company TWGMC. The output voltage of the AMS1117-3.3 is adjustable from 1.25V to 13.2V with a maximum dropout of 0.7V at full load. The voltage regulation is improved by its 2.0A peak current capability, thermal protection, and maximum operating temperature of 125°C. It also features a low quiescent current when in power save mode, and a fast–start turn-on time of 10µs. This makes the AMS1117-3.3 an ideal choice for designs requiring a high degree of reliability in an efficient, low-noise environment.
