Demonstration circuit 995A is an adjustable 1.1A linear regulator featuring the LT3080. Architected as a precision current source and voltage follower, it allows this new regulator to be used in many applications requiring high current, adjustability to zero output, and no heat sink. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. The demo board's input supply voltage range is 2.3V to 25V. For proper regulation, the LT3080 has a control pin; the voltage on this pin must be 1.2V to 1.35V higher than the output voltage.The output voltage is jumper selectable and can be set to 1.8V, a value between 0V and 5V (using trimpot R2) or a user-defined value. A key feature of the LT3080 is its wide output voltage range. By using a reference current through a single resistor, the output voltage can be programmed to any level between zero and 36V. The DC995A has a reduced input voltage 25V due to input capacitor voltage rating. The DC995A can be used as a high current linear regulator, a post regulator for switching supply,a  variable voltage supply or a low output voltage power supply.
