ELECTRICAL CHARACTERISTICS
(V I - V O = 5V, I O = 0.5A, 0°C ≤ T J ≤ +125°C, I MAX = 1.5A, P MAX = 20W, unless otherwise specified) *
Load and line regulation are specified at constant junction temperature. Change in V D due to heating effects must be taken into account separately. Pulse testing with low duty is used. (P
MAX = 20W)
