Automotive-rated boost regulator in a SOT-23-5 package
The Texas Instruments LM2735XQMF/NOPB is an automotive-grade (AEC-Q100 qualified) current-mode boost regulator that also supports flyback and SEPIC topologies. It integrates a 2.1 A switch and operates from a 2.7 V to 5.5 V input rail.
Package and thermal reality
Housed in a SOT-23-5 package, this part is small but thermally limited at high ambient. The junction temperature range of -40°C to 125°C covers under-hood and cabin automotive environments.
Lifecycle and sourcing posture
ROHS3 compliant. For BOM planning, this part is available through independent distribution and quoted to order against an RFQ — no allocation risk flagged at this time. The 'NOPB' suffix confirms lead-free / RoHS3 compliance; the 'XQ' prefix indicates the automotive-grade AEC-Q100 qualified variant.
