Samsung SR-608EV - MC7812 C Voltage Regulator Specs

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