FAQ:
Q: What is the best linear power converter for 12V to 9V?
A: Here we mainly use reliable linear power converters like LM7809 and LM317. LM7809 is a fixed voltage regulator IC that reduces and regulates the input voltage in electrical circuits. A voltage regulator 12v to 9v converter with IC LM7809 is implemented as shown in the schematic diagram below.
Q: How do you convert 12V to 9V DC?
A: The digits ‘xx ‘ represents the value of the o/p regulated volts. The 7809 IC gives 9V DC as the digit ‘ xx ‘ in last represents (09). Pin 1 is the input pin. Pin 2 is the ground pin. Pin 3 is the output pin. A 12v to 9v dc converter can also be made with a versatile IC LM317 linear voltage regulator.
Q: How to reduce 12V battery potential to 9V?
A: These circuits can also be used to step down or reduce 12v battery potential to 9v so as to use it with microcontroller modules or any IC’s. Here we mainly use reliable linear power converters like LM7809 and LM317.
Q: How many ohms are in a 9 Volt Zener diode?
A: A 12v battery, 10-ohm resistor ( ≥ 10 ohms), 9.1V zener diode ( 5W ), some wires or connectors. It is the most common circuit of zener diode in voltage regulator configuration. Design 9volt zener voltage regulator from a 12volt power supply source.
