Diode as a temperature compensation circuit for transistors
Both diodes and transistors are made of silicon. As the temperature T increases, the transistor Vbe decreases, ib=VCC-Vbe/R7+R5 ib increases
To power a TLC555, use TL431 to make a small power supply. The schematic diagram comes from the TL431 chip manual.
How to calculate the output current of this power supply
The blue box on the left of the picture below is a complete DC boost circuit, so what is the function of adding the red box circuit on the right? Please help me answer this question. Thank you!
