Switch Mode Power Supply Basics | Analog Devices
This power drop can be significant because dissipated power is equal to I LDO × (V IN - V OUT). For example, when stepping down a 100mA load from a 3.6V battery to a 1.8V output, 0.18W is dropped across the linear regulator. This power drop yields a low 50% efficiency, which reduces battery longevity by 50% (assuming ideal operation).
