Each type employs internal current limiting, thermal shut down and safe operating 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, these devices can be used with external components to obtain adjustable voltages and currents. Features O Output Current up to 1A O Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24 O Thermal Overload Protection O Short Circuit Protection O Output Transistor Safe Operating Area Protection Ordering Code: Product Number Output Voltage Tolerance Package Operating Temperature LM7805CT LM7806CT LM7808CT LM7809CT LM7810CT r4% 40qC - 125qC LM7812CT LM7815CT LM7818CT LM7824CT TO-220 LM7805ACT LM7806ACT LM7808ACT LM7809ACT LM7810ACT r2% 0qC - 125qC LM7812ACT LM7815ACT LM7818ACT LM7824ACT © 2005 Fairchild Semiconductor Corporation DS400018 www.fairchildsemi.com LM7805 • LM7806 • LM7808 • LM7809 • LM7810 • LM7812 • LM7815 • LM7818 • LM7824 • LM7805A • LM7806A • LM7808A •LM7809A • LM7810A • LM7812A • LM7815A • LM7818A • LM7824A 3-Terminal 1A Positive Voltage Regulator April 1999 LM7805 • LM7806 • LM7808 • LM7809 • LM7810 • LM7812 • LM7815 • LM7818 • LM7824 • LM7805A • LM7806A • LM7808A •LM7809A • LM7810A • LM7812A • LM7815A • LM7818A • LM7824A Internal Block Diagram www.fairchildsemi.com 2 Parameter Symbol Value Unit VI 35 V VI 40 V RTJC 5 qC/W Input Voltage (for VO = 5V to 18V) (for VO = 24V) Thermal Resistance Junction-Cases (TO-220) Thermal Resistance Junction-Air (TO-220) RTJA 65 qC/W Operating Temperature Range TOPR 0 a 125 qC 40 a 125 qC 0 a 125 qC 65 a 150 qC LM78xx LM78xxA Storage Temperature Range TSTG Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur.
