Samsung SR-L677EV - Electrical Characteristics Mc7812; Regulator(Mc7812 C)

REGULATOR(MC7812C)
ELECTRICAL CHARACTERISTICS MC7812
(Refer to test circuit, Tmin < Ti < Tmax, Vi = 500mA, Vi = 19V, Ci = 0.33㎌, Co = 1.0㎌ unless otherwise specified)
* Tmin < Ti < Tmax
MC78XXI : Tmin = -40℃, Tmax = 125℃
MC78XXC, T
min = 0℃, Tmax = 125℃
* Load and line regulation are specified at constant junction temperature. Changes in Vo due to heating effects must be taken into
account separately. Pulse testing with low duty is used.
