Linear Voltage Regulator Vs Switching. Linear regulators reject input ripple without adding additional ripple. Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity unlike linear regulators.

If the two are close the efficiency can exceed 90. Linear regulators reject input ripple without adding additional ripple. Switching regulators provide much higher efficiencies but they can be more complex and create switching noise.
The linear regulator is conceptually simple with low cost low noise plus excellent dynamic response and load regulation.
Also linear voltage regulator actually reduces output voltage ripple and doesn t emit radio frequency interference not as noisy as switching regulator so they are popular for powering noise sensitive devices as well. Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity unlike linear regulators. Which approach is best.
