3-TERMINAL FIXED VOLTAGE REGULATOR Shantou Huashan Electronic Devices Co.,Ltd.
7812
H7812 series three terminal positive Regulators available TO-220 package with several fixed output voltages, making them useful wide range applications. Each type employs internal current limiting, Thermal shut down safe operating area protection, making essentially indestructible. adequate heat sinking provided, they deliver over output current. Although designed primarily fixed voltage regulator, these devices used with external components obtain adjustable voltages currents.
