All Output Voltage Versions  
Electrical Characteristics (Continued)  
Specifications with standard type face are for TJ = 25˚C, and those with boldface type apply over full Operating Tempera-  
ture Range. Unless otherwise specified, VIN = 12V for the 3.3V, 5V, and Adjustable version and VIN = 24V for the 12V ver-  
sion. ILOAD = 100 mA.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is  
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.  
Note 2: Voltage internally clamped. If clamp voltage is exceeded, limit current to a maximum of 1 mA.  
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.  
Note 4: Typical numbers are at 25˚C and represent the most likely norm.
