Shantou Huashan Electronic Devices Co.,Ltd. 3-TERMINAL FIXED VOLTAGE REGULATOR H 7808A █ Description The H7808A 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 components to obtain adjustable voltages and currents. █ Features l Output current up to 1A TO-220 l Output Voltages of 8V l Thermal Overload Protection l Short Circuit Protection l Output Transistor Safe Operating Area Protection █ Absolute Maximum Ratings(Ta=25℃) 1―INPUT 2―GND 3―OUTPUT VI——Input Voltage (for VO =5V to 18V)……………… 35V RθJC——Thermal Resistance Junction-Cases………… 5℃/W Rθ JA ——Thermal Resistance Junction-Air………… 65℃/W T OPR——Operating Temperature Range…………… 0~125℃ T STG ——Storage Temperature Range…………… -65~150℃ 1 Shantou Huashan Electronic Devices Co.,Ltd.
