Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at T A = 25°C unless otherwise noted.

Notes:
1. Load and line regulation are specified at constant junction temperature. Change in V O due to heating effects must be
taken into account separately. Pulse testing with low duty is used.
2. C ADJ , when used, is connected between the adjustment pin and ground.
