Supply voltage spans 2.25V to 3.6V, so the same part works on a 3.3V or 2.5V rail without a separate regulator — one BOM line covers both power domains.
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1121BM2-020.0000T is a standard surface-mount footprint.
Yes, the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec.
