KA7818A Fairchild 3-terminal 18V 1A Positive Voltage Regulator Data Sheet
Download Datasheet for Fairchild KA7818A 3-pin 18V 1A Positive Voltage Regulator [30 pages Rev.5.0 7/13/00 2000 pdf/zip]
Description
KA7818A features:
* Output Current up to 1A
* Output Voltage of 18V
* Thermal Overload Protection
* Short Circuit Protection
* Output Transistor Safe Operating area Protection
* 2% Output Voltage Tolerance
* TO-220 package
The KA78XX/KA78XXA series of three-terminal positive regulator 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.
