LT1460S3 (SOT-23)
TYPICAL PERFORMANCE CHARACTERISTICS Characteristic curves are similar for most
LT1460S3s. Curves from the LT1460S3-2.5 and the LT1460-10 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.
