LT3080EMS8E-1#PBF

LT3080-1 is a low dropout linear regulator that incorporates an internal ballast resistor to allow direct paralleling of devices without the need for PC board trace resistors. The internal ballast resistor allows multiple devices to be paralleled directly on a surface mount board for higher output current and power dissipation while keeping board layout simple and easy. This device brings out the collector of the pass transistor to allow low dropout operation down to 350mV when used with multiple input supplies. It is capable of supplying a wide output voltage range. A reference current through a single resistor programs the output voltage to any level between zero and 36V. Internal protection includes current limiting and thermal limiting. It is widely used in application such as high current all surface mount supply, high efficiency linear regulator, post regulator for switching supplies, low parts count variable voltage supply, low output voltage power supplies etc.
