All room temperature limits are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely norm. (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 LM2595 is used as shown in the Figure 35 test circuit, system performance is shown in the test conditions column. 7.5 Electrical Characteristics – 3.3 V Specifications are for TJ = 25°C (unless otherwise noted).
