Absolute maximums are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than

those listed in the Performance/Functional Specifications Table is not implied nor recommended.

General Conditions for Device under Test unless otherwise specified:

Typical at ambient temperature +25°C, nominal line voltage and nominal load conditions; All models are specified with an external 220μF input capacitor and 1μF & 10μf capacitors across

their output pins.
