The Power . .. The Vision VOLTAGE REGULATOR 48. DESCRIPTION The 79HG negative 4 terminal adjustable linear voltage regulator is capable of delivering a continous load current in excess of -5 amperes over an output range of -24 to -2.11 volls. The 79HG has built-in protection features such as output current limiting and thermal overload . If external conditions exceed the 79HG's capabilities (see absolute maximums), the device temporarily shuts down protecting itself and the load circuit until the fault is removed. This feature eliminates costly additional protection circuilry as well as overly con- servative heat sinks typical of discrete high current voltage regulator designs. The 4 lead hermetic TO-204MA package, (formerly called T0-3) provides up to 50 watts of internal power dissipation. 4B) FEATURES @ Output Voltage adjustable from -24 to -2.11 volts @ -5.0A output current @ Internal Current and Thermal Overload Protection @ Low Dropout Voltage (typically 2.2V @ 5.0A) @ 50 W Power Dissipation Connection Diagram @ Metal 4 lead TO-204MA type package ‘TO-206 Type Package (Top View) @ Cose electrically isolated (floating) ogg Ce) 4% PRODUCT FAMILY PART NUMBER OUTPUT VOLTAGE DESCRIPTION T9HGSC -24 to -2.11V Commercial Temp T9HGSM -24 to -2.11V Militory Temp TSHGSP ~24 to -2.11V Military Process
