Low Vce sat BJT Power Savings Slide 9

This circuit is used to provide power to a Compact Flash card when the card is plugged into a computer or digital camera. Again, 1.0A will be used to keep the calculations simple. This MOSFET has an Rds(on) of 220mΏ resulting in a power dissipation of 220mW. The voltage loss from the MOSFET would be 220mV.
