Note 1:
Although the internal power dissipation is limited, the junction temperature must be kept below the maximum specified temperature in order to meet data
sheet specifications. To calculate the maximum junction temperature or heat sink required, use the thermal resistance values which follow the Equivalent Circuit
Schematic.
Note 2:
For a supply voltage less than 30V between V
a
and V
b
, the absolute maximum input voltage is equal to the supply voltage.
Note 3:
For military electrical specifications RETS759X are available for LM759H.
