1.5 - 35 Volt DC Regulated Power Supply

The simple method to power your projects is illustrated in the circuit diagram of a regulated power supply. This compact power supply delivers a stable voltage.

This regulated power supply circuit is designed to convert an unregulated input voltage into a stable output voltage suitable for powering various electronic projects. The circuit typically consists of a transformer, a rectifier, a filter capacitor, and a voltage regulator.

1. **Transformer**: The transformer steps down the input AC voltage to a lower AC voltage level, which is necessary for the subsequent rectification process. The turns ratio of the transformer must be chosen based on the desired output voltage and the specifications of the project.

2. **Rectifier**: The rectifier converts the stepped-down AC voltage into pulsating DC voltage. This is usually achieved using a bridge rectifier configuration, which consists of four diodes arranged in a bridge layout. This configuration allows for full-wave rectification, improving efficiency and reducing ripple voltage.

3. **Filter Capacitor**: After rectification, the output still contains some ripple voltage. A filter capacitor is connected in parallel with the load to smooth out this ripple, providing a more stable DC voltage. The capacitance value should be selected based on the load current and the acceptable ripple voltage.

4. **Voltage Regulator**: The last stage in the circuit is the voltage regulator, which ensures that the output voltage remains constant despite variations in load current or input voltage. Common voltage regulators include the 7805 for +5V output or the LM317 for adjustable output voltages. The regulator may require additional capacitors at the input and output to maintain stability.

Overall, this regulated power supply circuit is essential for providing reliable power to various electronic devices and projects, ensuring that they operate within their specified voltage ranges. Proper selection of components and careful design considerations will enhance the performance and reliability of the power supply.The easy way to power your projects Here is the circuit diagram of regulated power supply.
