Must you always use a resistor between most ic's out pin and a transistor?
Egin 3 of 555 to an npn transistor.
Say I need 200 milliamps going to base of tansistor mj150013.
The 555's output can supply 200 milliamps.
Can I run the 555's output to the transistor without a resistor?
Will that cause the ic to short (as current flows from base to emitter(earth)).
does the tranny act as a load from base to emitter?
Think I'm going on and on.
Thanks
