General Description
The MAX8704 high-current linear regulator uses an external n-channel MOSFET to generate low-voltage supplies for notebook computers. This linear regulator delivers an output voltage as low as 0.5V from an input voltage as low as 1.0V. Normally, this low input requirement would make the design of such a regulator very difficult. In this application, the 5V bias supply that is always available in the system powers the MAX8704 driver and control circuitry.
