79HG

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 volts. The 79HG has built-in protection features such as output current limiting and thermal overload lf external conditions exceed the 79HG's capabilities (see absolute maximums), the device temporarily shuts down protecting itself and the load circuit until the fault isremoved. This feature eliminates costly additional protectioncircuitry as well as overly conservative heat sinks typical of discrete high current voltage regulator designs. The 4 lead hermetic TO-204MA package, (formerly called TO-3) provides up to 50 watts of internal power dissipation.

The features of 79HG can be summarized as (1)output voltage adjustable from -24 to -2.1 volts; (2)-5.0 A output current; (3)internal current and thermal overload protection; (4)low dropout voltage (typically 2.2V @5.0A); (5)50W power dissipation; (6)metal 4 lead TO-204MA type package; (7)case electrically isolated (floating).

The absolute maximum ratings of 79HG are (1)input voltage: -40V; (2)input to output differential, output short circuited: -35V; (3)internal power dissipation 50W @25°C case; (4)operating junction temperature: 79HGSC (commercial) 0°C to 150°C, 79HGSM (mil temp) -55°C to 150°C, 79HGSP (mil process) -55°C to 150°C; (5)storage temperature range: -55°C to 150°C; (6)pin temp (soldering 60 sec): 300°C.
