How to Design a Circuit for a Constant 2.5V Output

To ensure a constant 2.5V output regardless of varying input voltages between 5V and 15V, you can use a voltage regulator IC like the LM317.

Circuit Diagram:

Components:

• LM317 Voltage Regulator
• Resistors
• Capacitors

Steps to Design the Circuit:

1. Connect the input of the LM317 to the varying input voltage source (5V to 15V).
2. Connect the output of the LM317 to the load with a constant 2.5V requirement.
3. Select appropriate resistors and capacitors to set the output voltage to 2.5V.
4. Add input and output capacitors for stability and filtering.
5. Test the circuit to ensure it maintains a constant 2.5V output within the specified input voltage range.

By following these steps and using an LM317 voltage regulator, you can design a circuit that provides a reliable and stable 2.5V output regardless of input voltage fluctuations.
