LT6660
W U TYPICAL PERFOR A CE CHARACTERISTICS Characteristic curves are similar for all voltage options of the LT6660. Curves from the LT6660-2.5 and the LT6660-10 represent the extremes of the voltage options. Characteristic curves for other output voltages fall between these curves, and can be estimated based on their voltage output. 2.5V Output Voltage 2.5V Supply Current Temperature Drift vs Input Voltage 2.5V Line Regulation
