CYStech Electronics Corp. Spec. No. : C521E3 Issued Date : 2003.04.02 Revised Date :2005.06.08 Page No. : 1/3 3-TERMINAL POSITIVE VOLTAGE REGULATOR LM7805XE3 Description The LM7805XE3 series of three-terminal positive regulators are available in the TO-220AB package. These regulators can provide TO-220AB 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. LM7805XE3 is characterized for operation from 0C to +125C, and if operating temperature is always high, please refer to the power dissipation curve.
