All room temperature limits are 100% tested during production with TA = TJ = 25°C. All limits at temperature extremes are specified via
correlation using standard Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
(2)
Typical values are determined with TA = TJ = 25°C and represent the most likely norm.

The peak switch current limit is determined by the following relationship: ICL=37,125/ RADJ.
6.9 Electrical Characteristics – All Output Voltage Versions
Specifications are for TA = TJ = 25°C unless otherwise specified. Unless otherwise specified VIN = 12 V for the 3.3-V, 5-V, and
Adjustable versions and VIN = 24 V for the 12-V version.
