Manufacturer:Raychem/tyco Description:CAPACITIVE LOADS Like most micropower circuits the LM45 has a limited ability to drive heavy capacitive loads The LM45 by itself is able to drive 500 pF without special precautions If heavier loads are anticipated it is easy to isolate or decouple the load with a resistor see Figure 4 Or you can improve the tolerance of capacitance with a series R-C damper from output to ground see Figure 5 Any linear circuit connected to wires in a hostile environ- ment can have its performance affected adversely by in- tense electromagnetic sources such as relays radio trans- mitters motors with arcing brushes SCR transients etc as its wiring can act as a receiving antenna and its internal junctions can act as rectifiers For best results in such cas- es a bypass capacitor from VIN to ground and a series R-C damper such as 75X in series with 0 2 or 1 mF from output to ground as shown in Figure 5 are often useful |
