Comparison of Linear Regulators (LDOs) and Switching Regulators

Design Considerations	Linear	Switching
Function	Only steps down (buck) so input voltage must be greater than output voltage	Step up (boost), step down (buck), inverts
Efficiency	Low to medium, but actual battery life depends on load current and battery voltage over time. Efficiency is high if difference between input and output voltages is small	High, except at very low load currents (μA), where switch-mode quiescent current (IQ) is usually higher
Waste heat	High, if average load and/or input to output voltage difference are high	Low, as components usually run cool for power levels below 10 W
Complexity	Low, usually requiring only the regulator and low-value bypass capacitors	Medium to high, usually requiring inductor, diode, and filter caps in addition to the IC; for high-power circuits, external FETs are needed
Size	Small to medium in portable designs, but may be larger if heatsinking is needed	Larger than linear at low power, but smaller at power levels for which linear requires a heat sink
Total cost	Low	Medium to high, largely due to external components
Ripple/Noise	Low; no ripple, low noise, better noise rejection	Medium to high, due to ripple at switching rate

*If you have an emphasis on a particular design consideration, the option in bold may be the product type that best suits your needs.
