ANMBEST Power Converters Editorial Review
The Anmbest 10 Pack 3 Pins AMS1117-3.3 DC 4.75V-12V to 3.3V Voltage Regulator Step Down Power Supply Buck Module 800mA is a step-down voltage regulator frequently used to convert input voltage down to help power appliances. This AMS1117 Module can reach an input voltage of 15V, but a maximum input voltage of 12V is recommended to prevent damage to the module. The product is said to be a voltage regulator with no provision for using a heat sink. The output voltage of the product cannot be changed from 3.3V. The product is recommended for use when handling small loads, anything above 50mA may need greater ventilation to avoid overheating. Notably, the product may have defects, and not all the units may work correctly. One common potential problem reported is that it fries the parts that it is powering. Testing before use is strongly encouraged.
