Integrated linear power supplies typically range from $30 to over $500 depending on voltage, current, and application.

Overview of Pricing

• Entry-level lab or hobbyist supplies: Small DC linear power supplies, such as 5–30V with 1–5A output, are commonly priced between $30 and $150 on platforms like Amazon and Mouser Electronics (e.g., KORAD KD3005D, KA3005D) for digital regulated lab-grade units .
• Embedded linear power supplies: Designed for embedded systems, these units provide low-noise, stable output for sensitive electronics. Prices typically range from $50 to $200, depending on power rating and form factor .
• High-end audio or specialized applications: Audio-grade DC linear power supplies, such as those from LHY Audio, can cost $200 to $500+, offering ultra-low noise and precise voltage regulation for high-fidelity systems .

Factors Affecting Price

1. Voltage and Current Ratings: Higher voltage or current capacity increases cost.
2. Precision and Noise Level: Low-noise or high-precision units for audio or lab use are more expensive.
3. Form Factor: Embedded or open-frame designs may be priced differently than benchtop units.
4. Brand and Features: Digital displays, adjustable outputs, and protection features (overvoltage, short-circuit) can add to the price.

Where to Buy

• Mouser Electronics: Offers a wide range of linear power supplies with datasheets and pricing for professional and hobbyist use .
