The L7809 of three-terminal positive regulators is available in TO-220, TO-220FP, TO-220FM, TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. The L7809 can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, the L7809 can be used with external components to obtain adjustable voltage and currents.
L7809 absolute maximum ratings: (1)VI DC Input Voltage for VO= 5 to 18V 35V; for VO= 20, 24V 40V; (2)IO Output Current Internally Limited; (3)Ptot Power Dissipation Internally Limited; (4)Tstg Storage Temperature Range: -65 to 150 ℃; (5)Top Operating Junction Temperature Range: for L7800 -55 to 150℃; for L7800C 0 to 150℃.
L7809 features: (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.
