The MAX1864 Generates 1.2V or Lower Output Voltage


Abstract:Article shows how a regulator can generate an output voltage that is less than the reference voltage. Circuit generates a
1.0V output voltage. The MAX1864 triple-output power supply is featured.

With most regulators, it is difficult to generate an output voltage that is less than the reference voltage. This note describes a way
to use the MAX1864 to achieve an output voltage less than its 1.236V reference.

The MAX1864 includes a positive linear regulator gain block. With a few external
