That fixed output means no external feedback divider — the BOM stays at one inductor, two ceramics, and the part itself. Switching at 2.25 MHz keeps the inductor in the 1–2.2 µH range, which fits the 6-WSON (2x2) footprint without crowding the output cap.
For a 105°C or 125°C ambient, look at the automotive-rated LM53625LQURNLRQ1 which runs to 150°C junction.
The part is ROHS3 compliant.
Ensures the regulator meets the system's voltage and load requirements.
Confirms long-term availability for production and maintenance planning.
Critical for prototypes and low-volume runs to find authorized distributors with stock.
Determines PCB layout compatibility, especially for the 6-WDFN exposed pad.
Helps source alternatives if the exact MPN is unavailable or for cost optimization.
Affects EMI, efficiency, and output ripple filtering design.
