DC1401A

DC1401A demonstration circuit is an adjustable 500mA linear regulator featuring LT®3085. 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. Also the device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. A key feature of the LT3085 is the capability to supply a 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 DC1401A has a reduced input voltage 25V due to input capacitor voltage rating. And DC1401A is capable of delivering up to 500mA output current. Therefore, the DC1401A can be used as a high current linear regulator, post regulator for switching supply, variable voltage supply or low output voltage power supply.

• Internal protection circuitry includes current limiting and thermal limiting
