This is a boost converter made with uc3843. Input is 24vdc and it goes to the circuit made with tl431 as a voltage regulator ( i don't know what to call this). I run this part of circuit in ltspice and found that with varying the voltage on the input side i get steady 10.77v on output (wire connecting to the vcc pin of 3843).
Question is, why not use a linear voltage regulator instead of this. I connected a 100ohm load to the output and the voltage dropped to something 6volts. This is not even capable of supplying 50mA then why to use such setup? Lm7810 or lm7812 are not good for this?
Please correct me if this is something other than voltage regulator, i really don't know, it is just a assumption i made after simulation.
