Descriptions
Descriptions of onsemi KA7812ETU provided by its distributors.
LINEAR VOLT REG, 1A, 12V, TO-220AB-3; Fixed Output Voltage Nom.:12V; Adjustable Min:-; Max:-; Input
Last Time Buy Positive Fixed ROHS3Compliant Linear Voltage Regulator IC -40C~125C 1A 35V
KA78 Series 11 V 1 A Fixed Flange Mount Voltage Regulator - TO-220-3
Standard Regulator Pos 12V 1A 3-Pin(3+Tab) TO-220 Rail
The KA78XXE/KA78XXAE 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.
