![]() ![]() You can connect two LEDs in series across the output of R2 resistor if you are using a 9volt battery as an input. The circuit shown here is the circuit for low current (1-30 mA) applications, suppose we have to take reference voltage for comparison or a very low current drawing circuit of an LED indicator. 9v to 5v converter using a voltage divider: The voltage divider circuit is not recommended for use in the high current application as it has a low output current and lower efficiency. These circuits are basic voltage regulators, the first one is simple voltage divider using resistors.Īll the circuits have different performance. I have listed all possible circuits but their application differs from circuit to circuit. Here are the simple circuits that provide +5V from a 9V radio battery. When working with a 9V battery supply, it becomes quite difficult to get a 5V dc power supply for the circuits. Before jumping to the 9v to 5v converter circuit using different schematics lets talk a bit about it.Ī wide range of IC’s and devices require 5 V DC supply for proper operation. ![]()
