BL78A05

BL78A05 Positive voltage regulators 1. Features Output current to 1.5 A Output voltage of 5V Thermal overload protection Short circuit protection Output transition SOA protection 2. Description The BL78A05 of three-terminal positive regulators is available in TO-220 package, making it useful in a wide range of applications. These regulators can provide lacal on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.5 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents Block diagram http://www.DataSheet4U.net/ 1 www.belling.com.cn Belling Proprietary Information.
