CYStech Electronics Corp. Spec. No. : C521F3 Issued Date : 2007.09.13 Revised Date : Page No. : 1/4 3-TERMINAL POSITIVE VOLTAGE REGULATOR LM7805XF3 Description The LM7805XF3 series of three-terminal positive regulators are available in the TO-263 package. These regulators can provide local on -card regulation, eliminating the distribution problems associated with single point regulation. Each employs internal current limiting, thermal shutdown 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.
