All limits specified at room temperature (standard typeface) and at temperature extremes (boldface type). All room temperature limits are

100% production tested. All limits at temperature extremes are ensured via correlation using standard Statistical Quality Control (SQC)

methods.

(2)

The output voltage range is 5V to 20V and is determined by the two external resistors, R1 and R2. See Typical Application Circuit.

(3)

Output current capability will decrease with increasing temperature, but will not go below 1A at the maximum specified temperatures.
