1 LM78XX / LM78XXA 3-Terminal A Positive oltage Regulator Features Output Current up to A Output oltages: 5, 6, 8, 9, 0,, 5, 8, 4 Thermal Overload Protection Short-Circuit Protection Output Transistor Safe Operating Area Protection Description September 04 The LM78XX series of three-terminal positive regulators is available in the TO-0 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. If adequate heat sinking is provided, they can deliver over A output current. Although designed primarily as fixedvoltage regulators, these devices can be used with external components for adjustable voltages and currents. TO-0 (Single Gauge) GND. Input. GND 3.

Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
