(2) All limits specified at room temperature TYP and MAX. All room temperature limits are 100% production tested. All limits at temperature extremes are specified through correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level. 6.10 Electrical Characteristics – Adjustable Version TJ = 25°C, and all MIN and MAX apply over full operating temperature range. VIN = 12 V, ILOAD = 100 mA (unless otherwise noted).
