  3. Circuits Supply Light Maxim MAX1698 MAX4040
    Portable systems often use LEDs of different colors and in varying quantities of each color. Some examples are white for the display backlight, green for keypad illumination, and red for power. Typically, the LEDs derive power from at least two ...

  2. Circuits Supply Maxim MAX4475 MAX6126 MAX8887
    Many low-dropout-voltage regulators see service in electronic systems, but relatively few are designed for low-noise operation. (For example, Maxim's MAX8887 achieves a noise voltage of approximately 42 µV rms.) However, certain ...
