。</small></p> <p class="text-info font-weight-bold"> ▸ 雜訊抑制能力 PSRR</p> <p>PSRR 是用來量化 LDO 對不同頻率的輸入電源紋波的抑制能力的，它反映了 LDO 不受雜訊和電壓波動、保持輸出電壓穩定的能力。PSRR 能力會與系統增益頻率有關係。在低頻率 10kHz 以下 ， LDO 具有很高的開環電壓增益，能對紋波形成非常有效的抑制。當超過某個單位增益頻率，LDO 便無法再消除波紋了，所以在高頻率處的紋波衰減，主要是藉由 LDO 輸出電容和它的內部寄生電容來完成</p> <p class="text-info font-weight-bold"> ▸ 低靜態電流（<15uA）</p> <p>靜態電流是指由 IC 內部的回饋控制和驅動電路所消耗的電流，透過量測流過 LDO 接地引腳的電流得知。如果休眠時電源消耗成為電池壽命關鍵的應用，便可選擇低靜態電流的線性穩壓器。</p> </div> <div class="col-md-12 "> <div class="mt-2"> <h5 class="font-weight-bold mb-40" >想了解更多 LDO 設計細節？</h5> </div> </div> <div class="col-md-12 ">
