LT3080/LT3080-1 Single Resistor LDOs

Analog Devices Inc. LT3080/LT3080-1 1.1A Low Dropout (LDO) Linear Regulators incorporate an internal ballast resistor that allows direct paralleling of devices without the need for PC board trace resistors. Keeping the board layout simple and easy, the internal ballast resistor allows multiple devices to be paralleled directly on a surface mount board for higher output current and power dissipation. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple input supplies.
