| Shantou Huashan Electronic Devices Co.,Ltd. H 7905 3-TERMINAL 1A NEGATIVE VOLTAGE REGULATORS The H7905 series of three terminal negative 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 area protection, making it essentially indestructible. Features Output current in Excess of 1A Output Voltages of -5V lntemal Thermal Overload Protection Short Circuit Protection Output Transistor Safe-Area Compensation 1D GND 2D INPUT 3D OUTPUT TO-220 Absolute Maximum Ratings Ta=25ae(c) VI R|E R|E JC JA Input Voltage - - - - - - - 5ae 65ae - -35V /W /W 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.
