Regulated power supply:
1. A regulated power supply maintains a constant output voltage regardless of changes in input voltage or load conditions.
2. It uses a feedback mechanism to adjust the output voltage to the desired level.
3. Regulated power supplies are more stable and reliable compared to unregulated power supplies.
4. They are commonly used in electronic devices that require a precise and stable voltage supply, such as computers, televisions, and audio equipment.
Unregulated power supply:
1. An unregulated power supply does not have a mechanism to maintain a constant output voltage, so the output voltage can vary depending on changes in input voltage or load conditions.
2. It typically consists of a transformer, rectifier, and filter capacitor to convert AC voltage to DC voltage.
3. Unregulated power supplies are simpler and cheaper to design and manufacture compared to regulated power supplies.
4. They are commonly used in applications where a precise voltage supply is not critical, such as powering simple electronic circuits or devices.

Regulated Power Supply:
- Definition: A power supply that maintains a constant output voltage regardless of changes in input voltage or load current.
- Purpose: Provides a stable voltage to electronic devices, ensuring proper operation.
- Components: Includes feedback circuits, voltage regulation devices (e.g., transistors, voltage regulators), and compensation networks to maintain voltage stability.
- Advantages:
- Stable output voltage
- Protection against voltage spikes and fluctuations
- Improved device performance and reliability
Unregulated Power Supply:
- Definition: A power supply that does not regulate the output voltage, typically delivering the same voltage as the input.
- Purpose: Can provide sufficient voltage for low-power devices or applications where voltage stability is not critical.
- Components: Usually consists of a transformer, rectifier, and smoothing capacitor.
- Advantages:
- Simplicity and low cost
- Can provide high currents
Differences:
| Feature | Regulated Power Supply | Unregulated Power Supply |
|---|---|---|
| Voltage Control | Maintains a constant output voltage | No voltage control |
| Voltage Stability | High voltage stability | Output voltage varies with input voltage and load current |
| Complexity | More complex with feedback circuits | Simpler construction |
| Cost | Higher cost due to additional components | Lower cost |
| Applications | Electronic devices requiring stable voltage | Low-power devices or non-critical applications |
| Protection | Provides protection against voltage spikes | No protection against voltage spikes |
| Efficiency | Can be less efficient due to regulation | Potentially more efficient without regulation |
