(1)

Typical numbers are at 25°C and represent the most likely norm.

(2)

All limits specified at room temperature (standard type face) and at temperature extremes (bold type face). All room temperature limits

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

(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(3)

External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect

switching regulator system performance. When the LM2596 is used as shown in the Figure 20 test circuit, system performance will be

as shown in system parameters of Electrical Characteristics section.
