1. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended
periods, may reduce device reliability.
2. Load and line regulation are specified at constant junction temperature. Change in VO because of heating effects is covered under
thermal regulation specification. Pulse testing with a low duty cycle is used.
