In conclusion, the best time to use a linear regulator is when noise in the system cannot be tolerated or when the VIN and VOUT difference is small. The best time to use a switching regulator is when the difference between VIN and VOUT is large. Also, it is best to use a switching regulator when efficiency is important and large currents are involved. Semtech has many options for both linear regulators and switching regulators.
