(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.

Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating  
Temperature Range. Unless otherwise specified, VIN = 12V for the 3.3V, 5V, and Adjustable version and VIN = 24V for the  
12V version. ILOAD = 500 mA

(3) The switching frequency is reduced when the second stage current limit is activated.  
(4) No diode, inductor or capacitor connected to output pin.  
(5) Feedback pin removed from output and connected to 0V to force the output transistor switch ON.  
(6) Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the ADJ. version, and 15V for the 12V version, to force  
the output transistor switch OFF.  
(7) VIN = 40V.
