Product details
The LM317 is a linear voltage regulator, not a DC-DC switching converter, and functions differently to step down voltage. A DC-DC switching converter, also known as a buck converter, typically offers higher efficiency, while the LM317 provides a more stable, low-noise output suitable for sensitive electronics.
LM317 linear voltage regulator circuit boards
The LM317 adjustable linear regulator is available on small circuit boards, often featuring a potentiometer for easy output voltage adjustment. These are simple to use for hobbyists and professionals who need a low-ripple, regulated DC voltage.
- LM317 DC-DC Step Down DC Converter Circuit Board (Generic): Available on sites like Nerdshed, this module includes the LM317 IC and a potentiometer.
- Input voltage: 4.2V–40V.
- Adjustable output voltage: 1.2V–37V.
- Maximum output current: 1.5A (typical).
- LM317 Adjustable Linear Regulator Module: Sold by Electra Store, this board is a good example of a linear regulator module intended for applications where low noise is a priority.
- Input voltage: 4V–40V DC.
- Adjustable output voltage: 1.25V–37V.
- Maximum output current: 1.5A (continuous 1A recommended).
Comparison: LM317 vs. switching DC-DC converters:
The distinction between linear regulators like the LM317 and switching converters is critical for your project's power efficiency and heat management.
| Feature | LM317 Linear Regulator | Switching DC-DC (Buck) Converter |
| Efficiency | Lower efficiency, especially with large input-output voltage differences. Excess power is dissipated as heat, requiring a heatsink for higher currents. | High efficiency, as it switches on and off to regulate voltage, reducing power loss. |
| Noise | Produces very low electrical noise (ripple), making it ideal for sensitive analog circuits, audio, and radio-frequency projects. | Generates more electrical noise due to its high-frequency switching action. |
| Heat Dissipation | Can generate significant heat, especially when the input voltage is much higher than the output voltage. Requires a heatsink for high-current applications. | Generates very little heat, even when dealing with large voltage differences. |
| Circuit Complexity | Very simple to use, requiring just a couple of external resistors for a basic circuit. | More complex circuitry involving an inductor, diode, and control IC, though pre-built modules simplify this. |
| Dropout Voltage | Has a higher "dropout" voltage (the minimum difference between input and output voltage), typically around 2V to 3V. | Can have a much lower dropout voltage, allowing for regulation even when the input and output voltages are close. |
When to choose an LM317:
Opt for an LM317 circuit board if your project requires:
- Low noise: For powering sensitive audio or analog circuits.
- Simplicity: A straightforward, reliable voltage regulation solution that is easy to implement.
- Moderate current draw: You are operating at lower currents where heat dissipation is less of a concern.
Alternative: Switching DC-DC buck converter:
If high efficiency is the most important factor for your application, such as in battery-powered devices, you should use a dedicated buck converter module instead. These modules are readily available from electronics retailers
