A voltage regulator with a very low drop-out voltage. The regulator utilizes an inversely biased metal-oxid semiconductor field effect transistor as a regulating element. The field effect transistor is linearly controlled by an error amplifier which compares the regulated output with a reference voltage. The field effect transistor creates a voltage drop between the input and the regulated output by a diode function within the field effect transistor. The field effect transistor bypasses this diode function with a linearly controlled resistance function to thereby create a regulated output.
A power converter provides power across an isolation barrier, such as through the use of coils. A coil driver has transistors connected in a positive feedback configuration and is coupled to a supply voltage in a controlled manner by measuring the output power and opening or closing a switch as needed between the power supply and the coil driver. An output circuit, such as a FET driver, can be used with or without isolation to provide power and a logic signal.
