The LT3008’s low dropout voltage allows for higher efficiency operation as the differential between input and output is minimized, reducing power dissipation. Battery life in portable products may be increased as the battery input voltage may be run down closer to the output voltage, and still maintain V_OUT regulation. In addition, it’s no-load quiescent current is approximately 3μA at 25°C. Ground pin current remains at less than 5% of output current as the load increases. In shutdown, quiescent current is less than 1μA.
