10Gids Commentaar
In practise, the efficiency of an LDO regulator is dependent on how much voltage it is dropping. While operating, an LDO is effectively a resistor that varies in real-time to ensure its output voltage stays stable despite changes in load current.
Power = I (current) x V (voltage)
Since an LDO is a resistive element, yes, it burns off energy as heat in this process. So an LDO dropping 18V to 5V could be very inefficient, more so when driving a higher current load as shown by the formula above. However, if an LDO is used to generate a 3.3V rail from a 5V rail, it is dropping just 1.7V, resulting in less power dissipation for the same load current.
You’re right, using an LDO for a large voltage drop is not good electrical design. But LDOs have excellent noise rejection performance, meaning they can take a noisy rail from a switching buck/boost converter with lots of transient or high-draw components on it, and create a much cleaner rail for lower-current, more sensitive devices. This is what I expect Apple’s doing.
LDOs drop the difference in voltage as heat, yes - hence the voltage difference between input and output determines the efficiency (eg a 3.0v LDO fed by 6.0v is 50% efficient).
In many cases where LDOs are used in designs the amount of lost power is negligible as the current being drawn is so small - simply not worth using a switcher for that rail. Also, LDOs typically have cleaner output so often an LDO is used to isolate an analog subsystem from noise on the main (digital) system rails.
