The ME2108A28PG with DC-DC Converters SOT-89 RoHS is a surface-mount DC-DC converter manufactured by Micro One. It is a step down type of DC-DC converter, meaning it takes in a higher, unregulated voltage and reduces it to a lower, regulated voltage. It has a 2V to 8V input voltage range and an adjustable internal output voltage ranging from 0.8V to 5.5V. The maximum output current is 180mA with a switching frequency of 250kHz. It is a RoHS compliant product, meaning it meets restrictions on the use of hazardous materials. It is housed in an SOT-89 package and typically used for powering ASICs, FPGAs, and microprocessors.
