Product may not necessarily be tested across the full temperature range and all parameters may not necessarily be tested. In the absence of specific PARAMETRIC testing, product performance is assured by characterization and/or design." (2) All limits ensured 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 specified via correlation using standard Statistical Quality Control (SQC) methods. (3) External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM2575EP is used as shown in the Figure 25 test circuit, system performance will be as shown in system parameters section of Electrical Characteristics.
