summary:



The cleanliness and response speed of the power supply in the audio system, especially the high requirements for power supply phase noise in the digital circuit and the influence of analog circuit power supply on the sound quality and timbre are very important. The core of this product is the Lingte LT high-end linear regulator chip LT3045/LT3094, which is ultra-low noise, 2-3 levels lower than the LM317, LM78xx, LM79xx and other regulated noise., It can provide you with very pure and fast energy for the audio circuit, so as to ensure the correctness of the sound quality and timbre performance, make the sound quality background darker and better in detail, make the low-frequency texture and elasticity stronger, and reduce some rough, harsh and hard lines in the middle and high frequencies, making it more delicate and smooth.

The noise of this chip is only 0.8uVRMS, which is far lower than the noise when the battery is working (the noise is about 2.7uV when the 3.7v lithium battery is loaded with 500mA). At the same time, the low frequency band of this chip is nearly 100dB, and the ultra-high power ripple suppression capability of 76dB at 1Mhz can eliminate the interference from power supply

Suitable circuit:



It can provide pure power supply for high-precision measuring instruments, HiFi audio DAC decoder, front stage, ear amplifiers and other small single stream load equipment



Replacement:



Directly replace LM78xx/79xx series, replace LT317/337 or LT1085, LT1963 and other three terminal regulators, or directly consult us (there is a replacement tutorial at the bottom of the details).

reminder:



If the original LM78 79 317 337 and other chips do not need a radiator, this voltage stabilizing module can be directly replaced and upgraded without a radiator. If the load current of the original circuit is large (0.2~0.5A), the module may need a radiator.
