Notes

➀

Typical at TA = +25°C under nominal line voltage and full-load conditions. All models are speci-

fied with an external 1μF multi-layer ceramic and 10μF capacitors across their output pins.

➁

Over-current protection is non-latching with auto recovery (Hiccup)

➂

Regulation specifications describe the output voltage changes as the line voltage or load current

is varied from its nominal or midpoint value to either extreme.
