Ian Canada LinearPi Pro Dual Ultra-Low Noise Linear Power Supply Module +/-12V
The LinearPi Pro, an evolution of the Linear Pi MKII, is a Ian Canada ultra-low-noise linear power supply capable of delivering high currents. This is the dual model corresponding to reference #38D. This regulated linear power supply is able to deliver +/-12V. Its ability to deliver a current of 5A makes it the perfect ally for modules requiring high currents, such as the Raspberry Pi5.
Key points and improvements of the IAN CANADA LinearPi Pro :
- 5A continuous output current
- Ultra-low output impedance of 2.5mOhm
- Very low noise level 0.8uV
- Parallel output architecture
- 4-layer PCB with double copper thickness and additional shielding layers
- Total filtering capacity 29080 uF
- Large heat sink
- SMT PCB assembly process
- Several LinearPi Pros can be grouped into a large power supply system using the integrated isolated master/slave on-off control signal chain

IAN CANADA LinearPi Pro Dual: excellent transient response
One of the key features of the Linear Pi Pro Dual is its transient load response. Indeed, when the load current varies from 1A to 5A, the noise level remains extremely low and the output voltage drop does not exceed 10mV. With output impedance limited to 2.5mOhm (@1kHz), the linear Pi Pro can be considered one of the best-performing low-noise linear power supplies on the market.
