This PDF data sheet is for the Fairchild MC7818 18V 1A Positive Voltage Regulator.
Fairchild Semiconductor MC7818 3-Terminal 18V 1A Positive Voltage Regulator
– Output Current up to 1A
– Thermal Overload Protection
– Short Circuit Protection
– Output Transistor Safe Operating Area Protection
The MC78XX series of three terminal positive regulators are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. 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.
