(1) All limits specified at room temperature (standard type face) and at temperature extremes (bold type face). All limits are used to
calculate Average Outgoing Quality Level, and all are 100% production tested.
(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 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 LM1575/LM2575 is used as shown in the test circuit Figure 25 and Figure 26, system performance will be as shown in system
parameters of Electrical Characteristics.
