(1) When the LM2825 is used as shown in Figure 17 test circuit, system performance will be as shown in Electrical Characteristics.
(2) Typical numbers are at 25°C and represent the most likely norm.
(3) All limits ensured at room temperature (standard type face) and at temperature extremes (bold type face) when output current is limited
to the value given in the temperature derating curves. See the Application Information section for curves. All limits at temperature
extremes are ensured using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing
Quality Level (AOQL).
