Question
Refer to the figure above. This circuit is brought in for repair. The measured output voltage was 25 V under all load conditions. A possible cause of this symptom might be that
Most voltage regulators include some kind of protection circuitry.
To get more output voltage from a step-down switching regulator, you have to
A voltage regulator with a no-load dc output of 15 V is connected to a load with a resistance of 12 . If the load voltage decreases to 14.5 V, the percent regulation would be
The LM317 regulator provides a(n)
R2 has opened. 91 25 y Vout R2 47ks2 4.1V 12 ks2 R7Explanation / Answer
1.
The supply voltage is dropped as output voltage. It is possible when emitter is opened so that the total voltage is dropped across the open circuit.
So, if base-emitter of Q1 is opened, the total voltage is dropped across the open circuit.
Vout = 25 V
So, option B is correct.
