Supply voltage spans 2.25V to 3.6V, so the same part can run on a 2.5V, 3.0V, or 3.3V rail without a separate LDO. It covers office equipment, networking gear, test instruments, and outdoor telecom cabinets in temperate climates, but not engine-bay or downhole applications.
Listed as Active by Microchip. The base product number is DSC1121. If a cross-reference is needed, confirm pinout and function against the target alternative — the 6-VDFN footprint is specific.
6-VDFN package — board layout notes
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount mounting. The 0.50 mm pitch (implied by the 6-lead VDFN) demands careful solder-paste stencil design to avoid bridging; a 0.15 mm stencil thickness with 1:1 aperture-to-land ratio is a typical starting point.
