Demonstration circuit 865 is an ultralow input voltage and dropout voltage supply using the 500mA output current LT3021 linear regulator, which comes in a 16-pin DFN package. The DC865 has an input voltage range from 1V to 10V and a jumper-selectable output voltage of 0.8V, 1.2V, 1.5V 1.8V or a user-determined value between 0.2V and 10V (minus the dropout voltage). Due to the 0.2V reference of the LT3021, the DC865 is capable of supplying power to very low voltage applications, such as (relatively) high current voltage references.
