If adequate heat sinking is provided, they can deliverover 1A output current. Although designed primarily as fixedvoltage regulators, these devices can be used with externalcomponents to obtain adjustable voltages and Current up to 1A OOutput Voltages of 5, 6, 8, 9, 12, 15, 18, 24 OThermal Overload Protection OShort Circuit ProtectionOOutput Transistor Safe Operating Area Protection Ordering Code:Product NumberOutput Voltage TolerancePackageOperating TemperatureLM7805 CTr4%TO-220 40qC - 125qCLM7806 CTLM7808 CTLM7809 CTLM7810 CTLM7812 CTLM7815 CTLM7818 CTLM7824 CTLM7805 ACTr2%0qC - LM7806 LM7808 LM7809 LM7810 LM7812 LM7815 LM7818 LM7824 LM7805A LM7806A LM7808A LM7809A LM7810A LM7812A LM7815A LM7818A LM7824 AInternal Block LM7806 LM7808 LM7809 LM7810 LM7812 LM7815 LM7818 LM7824 LM7805A LM7806A LM7808A LM7809A LM7810A LM7812A LM7815A LM7818A LM7824 AAbsolute Maximum Ratings(Note 1)Note 1.
