www.belling.com.cn V1.0 Page1 3-Terminal 1A Positive Voltage Regulator BL78XX GENERAL DESCRIPTION The BL78XX series of three-terminal positive regula tor are available in the TO-220 package and with several fixed output voltag es, 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.

www.belling.com.cn V1.0 Page9 APPLICATION CIRCUIT Notes : (1) To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and the Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage. (2) Ci is required if regulator is located an appreciable distance from power Supply filter. (3) Co improves stability and transient response.
