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 LM7805CT LM7806CT LM7808CT LM7809CT LM7810CT LM7812CT LM7815CT LM7818CT LM7824CT LM7805ACT LM7806ACT LM7808ACT LM7809ACT LM7810ACT LM7812ACT LM7815ACT LM7818ACT LM7824ACT TO-220 Output Voltage Tolerance Package Operating Temperature r4% 40qC - 125qC r2% 0qC - 125qC © 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 Internal Block Diagram www.fairchildsemi.com 2 LM7805 • LM7806 • LM7808 • LM7809 • LM7810 • LM7812 • LM7815 • LM7818 • LM7824 • LM7805A • LM7806A • LM7808A •LM7809A • LM7810A • LM7812A • LM7815A • LM7818A • LM7824A Absolute Maximum Ratings(Note 1) Parameter Input Voltage (for VO = 5V to 18V) (for VO = 24V) Thermal Resistance Junction-Cases (TO-220) Thermal Resistance Junction-Air (TO-220) Operating Temperature Range LM78xx LM78xxA Storage Temperature Range TSTG Symbol VI VI RTJC RTJA TOPR Value 35 40 5 65 0 a 125 Unit V V qC/W qC/W qC qC qC qC 40 a 125 0 a 125 65 a 150 Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur.

The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage. Note: CI is required if regulator is located an appreciable distance from the power supply filter. Note: CO improves stability and transient response.
