H7808
H7808 is 3-TERMINAL FIXED VOLTAGE REGULATOR manufactured by Huashan.
Description
The H7808 series of three terminal positive Regulators 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 1A output current. Although designed primarily as fixed voltage regulator, these devices can be used with external ponents to obtain adjustable voltages and currents.
