BL7805

BL7805 3-Terminal 1.2A Positive Voltage Regulator GENERAL DESCRIPTION The BL7805 series of three-terminal positive regulator are available in the TO-220 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 1.2A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. FEATURE Output Current up to 1.2A Thermal Overload Protection Short Circuit Protection Output Transistor Safe Operating Area Protection Output Voltages : 5V PIN CONNECTIONS BLOCK DIAGRAM Shanghai Belling Corp., Ltd.
