High performance DAC and fake LDO, how to get success? I working with ES9038Q2M DAC which really need high class LDO IC for power 3.3V. However, after 3 attempts to get tps79133 and ADP150 on ta08a0, I got 3 times fake, and very bad fake! PSRR was 2 times less than AMS1117, which is cheapest on the market LDO. So they selling 100% garbage with 28db PSRR(that's typical regulation quality for 2 transistors and 1 zener circuity), and your DAC will work much better even with AMS1117. My question addressed to DAC diyers, guys, where you buying an original LDO? I happy only with MPS LDOs which are cheap and good but never fake due to the company not so famous. Actually, ADP150 is also not expensive(30 cents) and I see no reason to make fake of that at all!
高性能DAC和假LDO,如何获得成功? 我使用的是ES9038Q2M DAC,它真的需要高功率的3.3V DCO IC。 但是,经过3次尝试在ta08a0上获得tps79133和ADP150后,我得到3次假装,非常糟糕假! PSRR比AMS1117低2倍,AMS1117是市场上最便宜的LDO。 因此,他们以28db PSRR(这是2个晶体管和1个齐纳电流的典型调节质量)销售100%垃圾,即使使用AMS1117,您的DAC也能更好地工作。 我的问题是针对DAC diyers,伙计们,你在哪里购买原装LDO? 我只对MPS LDO感到高兴,因为公司并不那么出名,所以它既便宜又好又不假。 实际上,ADP150也不贵(30美分),我认为没有理由假装它! |
