| 3-TERMINAL FIXED VOLTAGE REGULATOR Shantou Huashan Electronic Devices Co.,Ltd. H 7809 Description The H7809 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 Output current up to 1A Output Voltages of9V Thermal Overload Protection Short Circuit Protection Output Transistor Safe Operating Area Protection 1D INPUT 2D GND 3D OUTPUT 5ae 65ae 35V /W /W TO-220 VI R|E R|E Absolute Maximum Ratings Ta=25ae(c) Input Voltage (for VO=5V to 18V)- JC JA Thermal Resistance Junction-Cases- Thermal Resistance Junction-Air- Operating Temperature Range- Storage Temperature Range- - TOPR TSTG 0~125ae -65~150ae 1 Shantou Huashan Electronic Devices Co.,Ltd.
