L7812

The L7812 is designed as the three-terminal positive regulators which is available in TO-220,TO-220FP,TO-220FM,TO-3 and several fixed output voltages, making it useful in a wide range of applications.It can provide local on-card regulation,eliminating the distribution problems associated with single point regulation.Although designed primarily as fixed voltage regulators,these devices can be used with external components to obtain adjustable voltage and currents.

Features of the L7812 are:(1)output current to 1.5A;(2)output voltages of 5; 5.2; 6; 8; 8.5; 9; 10; 12; 15; 18; 24V;(3)thermal overload protection;(4)short circuit protection;(5)output transition SOA protection.

The absolute maximum ratings of the L7812 can be summarized as:(1)DC input voltage for VO=5 to 18V:35 V;(2)DC input voltage for VO=20,24V:40 V;(3)output current:internally limited;(4)power dissipation:internally limited;(5)storage temperature range:-65 to 150 °C;(6)operating junction temperature range:-55 to 150°C or 0 to 150°C;(7)thermal resistance junction-case max:3 or 5 or 4°C/W;(8)thermal resistance junction-ambient max:62.5 or 50 or 60 or 35°C/W.If you want to know more information such as the electrical characteristics about the L7812,please download the datasheet in www.seekic.com .
