... Telephone Ring Generator The PA44 is set for a gain of 38.5 boosting the 2.33V signal to 90V. The recommended compensation for gains above 30 is used. If capacitive loading is at least 330pF at all times, the recommended snubber network may be omitted. The 27 ohm resistor sets current limit to a nominal value of 111mA to insure peak currents out of at least 78mA ...

... The solder connection of the heatslug to a minimum 1 square inch foil area of the printed circuit board will result in thermal performance of 25°C/W junction to air rating of the PA44. Solder connection to an area square inches of foil is recommended. This may be adequate heatsinking but the large number of variables involved suggest temperature mea- surements be made on the top of the package ...
