Note 1: Absolute Maximum Rating indicate limits beyond which damage to the device may occur. Operating Rating indicate conditions for

which the device is intended to be functional, but do not guaranteed specific performance limits. For guaranteed specifications and

test conditions, see the Electrical Characteristics.

Note 2: The human body mode is a 100pF capacitor discharged through a 1.5k resistor into each pin.

Note 3: Typical number are at 25 : and represent the most likely norm.

Note 4: All limits guaranteed 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 guaranteed via correlation using standard Statistical

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

Note 5: External component such as the catch diode, inductor, input and output capacitors, and voltage programming resistor can affect

switching regulator system performance. When the G5ELM2596 is used as shutdown in the Figure 1 test circuit, system

performance will be as shown in system parameters section of Electrical Characteristics.

Note 6: The switching frequency is reduced when the second stage current limit is activated. The amount of reduction is determined by the

severity of current over-load.

Note 7: No diode, inductor or capacitor connected to output pin.

Note 8: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.

Note 9: Feedback pin removed from output and connected to 12V for the Adjustable, 3.3V and 5V versions, and 15V for the 12V version,

to force the output transistor switch OFF.

Note 11: Junction to ambient thermal resistance (no external heat sink) for To-220 package mounted vertically, with the leads soldered to a
