linear power supply LPS output DC5V USB 5V 3A, Ultra-Low Noise and Stable circuit
GOOD for upgrade to Raspberry pi 3 or SMSL M8A
Power supply is very important for sensitive device such as DAC or USB converter, USB power supply or switch power adapter have not very good influence, this stable linear power supply will help you to resolve problem and upgrade your device
Result of comparison between with switching power supply and this linear power:
Performance when use with linear power is much more clearly , sound background is transparent and quiet.
There is no insufficient that when use with switching power supply,which sound cold, hard,low frequency not good

>>Please Note:
(1) cause temperature,external power supply and display accuracy limit,
error 1-2% on display module is normal when power no-load
for example, 8V but display 8.2V, it is normal.
(2) and load error 5% is normal
