KA317 / LM317 - 3-Terminal Positive Adjustable Regulator Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the remended operating conditions and stressing the parts to these levels is not remended. In addition, extended exposure to stresses above the remended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted. Symbol Parameter Value Unit - VO TLEAD TJ TSTG...
