PROPER CARE IN USING IC LA 4440: Proper Cares in Using IC
· Maximum ratings:
If the IC is used in the vicinity of the maximum ratings, even a slight variation in conditions may cause the maximum ratings to be exceeded, thereby leading to breakdown. Allow an ample margin of variation for supply voltage, etc. and use the IC in the range where the maximum ratings are not exceeded.
Printed circuit board:
When making the board, refer to the sample printed circuit pattern and be careful that no feedback loop is formed between input and output.
Oscillation preventing capacitor:
Normally, a polyester film capacitor is used for 0.1mF + 4.7W. The capacitance value can be reduced to 0.047mF depending on the stability of the board·
Others: Connect the radiator fin of the package to GND.
