Package)
A key feature of the LT3080 is the capability to supply a n <1mV Load Regulation wide output voltage range. By using a reference current n <0.001%/V Line Regulation through a single resistor, the output voltage is programmed n Minimum Load Current: 0.5mA to any level between zero and 36V. The LT3080 is stable n Stable with 2.2µF Minimum Ceramic Output Capacitor with 2.2µF of capacitance on the output, and the IC uses n Current Limit with Foldback and Overtemperature small ceramic capacitors that do not require additional Protected ESR as is common with other regulators. n Available in 8-Lead MSOP, 3mm × 3mm DFN, 5-Lead DD-Pak, TO-220 and 3-Lead SOT-223 Internal protection circuitry includes current limiting and thermal limiting. The LT3080 regulator is offered in the
