LT1460
Typical Performance Characteristics Characteristic curves are similar for all voltage
options of the LT1460S3. Curves from the LT1460S3-2.5 and the LT1460S3-10 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.
