Vin is the source voltage. Pick any resistor value either R1 or R2 also depends on load impedance and solve for other. Then choose the nearest std. The circuit shown below zener voltage regulator schematic, it is useful for mA medium current drawing circuit eg.
LED indicators, transistor switches, Arduino, etc. Use this 12v to 9v converter DC to DC circuit with any other circuit across the 9. You will get about 9. Important: The load must be connected to the output end to prevent zener from getting damaged.
Series resistor 10 ohm is a current limiting resistor and when high current is drawn it has to pass that current through it, thus 5-watt resistor is necessary.
Working: It is the most common circuit of zener diode in voltage regulator configuration. Design 9volt zener voltage regulator from a 12volt power supply source. The maximum power rating …. For detail calculation and formulae search for 9v to 5v converter article on this website. These types of schematics are outdated but still found in several peripherals. This is the transistor-zener voltage regulator in EC mode:.
Blog , Circuits. If you are searching for the correct method to charge battery then you landed on the correct post article. You find these batteries everywhere in most of the devices we use […].
Schematics of the simple 12V to 6V converter circuits are discussed below. Below 12v to 6v reducer can be useful in case you want to replace your 6v battery with a 12 […].
This article will take you through all the aspects of a power bank circuit at home, with an in-depth steps to building power bank along with different modules, circuit board, connection diagram, and external case to use with it.
Nowadays it has become very impossible not to have a portable charger, alternate power source to […]. Before getting to 12v to 5v converter circuit using different methods lets a glance at the need of 5 volt supply.

LM is a fixed voltage regulator IC that reduces and regulates the input voltage in electrical circuits. The circuit will turn working in the opposite way. The base-emitter voltage of Q2 will rise, it is more working. Which causes Q1 more work too. When the output current rises up.
The current flows through Q2 rises too. Which causes the power transistor-Q1 more works. And the current flows through R3, VR2 is higher, too. But the current flows D1, D2 to reduces down. This causes Q2, Q1 comes back to low working again. Thus the output voltage is low voltage, too.
It makes the maximum output current is 4A. We can adjust the current with VR1, in 0. This circuit is small. I hope you are fun with it. If you have tested it gets a result, do not forget to share with me.
This circuit designs for modifying a 12V power supply input 12V from a battery or the other. By this circuit gives usual equipment, seek easy. Be integrated circuit IC and power transistor 2N Besides this circuit still can find to differ out voltage with well and have picture stability although load modifies. The Zener diode 8. The circuit that sees this is the power supply 6V to 9V Input 12V of a calculator. That has to prevent something through the circuit.
The part that performs to heal strong a picture uses the integrated circuit op-amp multi-purpose numbers in the character comparator mode. The circuit protects output compose transistor Q1-Q3.
By transistor, Q1 performs acknowledge voltage straddle Resistor R3. Which work when have current about mA or more than flow through R3 when TR1 work pick load C3, as a result, will do way resister package R5 10K values and thereafter 2 railings second.
The voltage will enough encourage. Q1 which cooperates with Q2 assembles be Transistor many rapidities are only. I always try to make Electronics Learning Easy. Your email address will not be published.
