Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

1. Load and line regulation are specified at constant temperature. Change in V_O due to heating effects must be taken into account separately.
Pulse testing with low duty cycle is used.
2. B = T_low to T_high, −40°C < T_J < 125°C C = T_low to T_high, 0°C < T_J < 125°C.
