LM317AHV Rev. 1.1.0 www.fairchildsemi.com LM317AHV — 3-Terminal Positive Adjustable Regulator September 2014 Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25В°C unless otherwise noted. Symbol Parameter Value Unit VI -VO Input-Output Voltage Differential 60 V TLEAD Lead Temperature 230 В°C 0 to +125 В°C TJ
