Absolute Maximum Ratings

Electrical Characteristics

(VI - VO = 5V, IO = 40mA, 0

°C ≤ TJ ≤ +125°C, PDMAX = 625mW, unless otherwise specified)

• Load and Line regulation are specified at constant junction temperature. Change in VO due to heating effects must be taken

into account separately. Pulse testing with low duty cycle is used.
