My friends,
My topic is in very basic section- "Voltage Divider"
As part of academic project, I need 5V, 3.3V, 0.5V supply accurately without any change. I planned to implement a simple power supply generation circuit of +5V and thereafter use Voltage Divider to get 3.3V, 0.5V. Approximate current taken by regulator will be 20mA-50mA, and we are using 50mA rating Stepdown transformer. IC also needs current requirement of max. 50mA. Will there be any problem. Will the same 20-50mA current will be available practically at divided voltage section?
For better accuracy, will implementation using high precision resistors (in divider section) be sufficient or should I need to use separate reulator for other voltages?
Waiting for your reply :|,
