The SD8910 is a DC-DC Converters SOT-23-6 (small outline transistor, 23 pins, 6 leads) manufactured by SHOUDING. It is a surface mount, step-down type switching regulator, which has a wide input voltage range of 4.5V to 28V, and is able to accurately set the output voltage from 0.6V to 18V with a ±2% accuracy. It has two integrated operational amplifiers, one for controlling the output up and one for controlling the output down, as well as the ability to safely withstand continuous short-circuits and transients. It is RoHS (Restriction of Hazardous Substances) compliant and has low EMI (electromagnetic interference) characteristics.
