	It is important to know and understand that an [[LDO]] does this by "burning of" the excess voltage and this can and does result in quite a lot of heat which must be handled in the design. The amount of energy burned off is easy to calculate. Let's imagine using a 3.3V regulator from a 5V source. The voltage drop over the regulator is 5V - 3.3V = 1.7V. If using 100 mA that would result in 1.7V * 0.1A = 0.17W (or 170 mW) of power.

		+	When running the simulation it is quite easy to understand how it functions. The output voltage is controlled by a N-channel MOSFET which is being controlled by an opamp. The opamp acts like a comparator which compares an internal voltage reference (in the simulation that is a Zener diode) with the output voltage divided down to an appropriate level.
