Hi,
im new to the forum and am studying electrical energy engineering. A minor module we study is 741 operational amplifiers. I have an exam on the 11th of Jan and need help with the following 2 questions. Ive searched google and this forum and cant find an answer that will do. The questions are from past exam papers and are as follows:
1 - What is meant by maximum power dissipation and drop-out voltage when associated with integrated circuit voltage regulators. A voltage regulator has a drop out voltage of 2V and a maximum power dissipation of 2W. Determine the maximum and minimum voltage which can be applied to a 12V regulator when conducting a current of 100mA.
2 - Sketch to scale the asymptotic and actual bode frequency response for a direct coupled amplifier with a cutoff frequency of 100kHz and a passband gain of 10. Why is the amplitude expressed in dB's? At what frequency is the gain 0dB's.
Thats it, sorry if they seem really easy, its my first year and I find electronics harder than electrical circuit theory. Any help will be greatly appreciated.
