Pin-compatible alternative with higher current, but review quiescent current for battery or standby applications.
The LMR16030SDDAR is a 60V, 3A step-down voltage regulator from Texas Instruments in an 8-HSOIC package. Key alternatives include pin-compatible options from TI's TPS54x60B family, which offer similar or higher performance but may have different quiescent current.
Higher quiescent current impacts standby power.
Pin-compatible options with the same thermal PowerPAD are available.
These are hardware-configured regulators, no firmware changes needed.
Direct replacement for LMR16030SDDAR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for LMR16030SDDAR, then review parametric alternatives for package and electrical fit.
The primary risk is the increased quiescent current in alternatives like the TPS54x60B series, which can reduce efficiency in light-load or battery-powered systems.
