MC7812

The MC7812 is one member of the MC78XX series whcih designed as one kind of three terminal positive regulators that can be used in the TO-220/D-PAK package and with several fixed output voltages, making MC7812 useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible.

Features of the MC7812 are:(1)output current up to 1A;(2)output voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V;(3)thermal overload protection;(4)short circuit protection;(5)output transistor safe operating area protection.The absolute maximum ratings of the MC7812 can be summarized as:(1)input voltage (for VO=5V to 18V):35 V;(2)input voltage (for VO=24 V):40 V;(3)thermal resistance junction-cases (TO-220):5 /W;(4)thermal resistance junction-air (TO-220):65 /W;(5)operating temperature range:0 to +125;(6)storage temperature range:-65 to +150;(7)quiescent current:5.1 mA;(8)output voltage drift:-1mV/;(9)output noise voltage:76 V/Vo;(10)peak current:2.2 A.If you want to know more information such as the electrical characteristics about the MC7812,please download the datasheet in www.seekic.com or www.chinaicmart.com .
