National Semiconductor LM1085 3A Low Dropout Positive Regulators Datasheet
The LM1085 is a series of low dropout positive voltage regulators available in adjustable and fixed voltage versions (3.3V, 5.0V, and 12.0V). It features a maximum dropout of 1.5V at 3A of load current and shares the same pin-out as the industry standard LM317. The device includes a zener trimmed bandgap reference, current limiting, and thermal shutdown protection.
