選擇一款電源管理器件，需要根據實際應用場景去權衡不同的參數指標。在對電源輸出紋波有比較高要求的射頻和無線等應用，我們就需要著重考量電源管理器件的電源抑制比（PSRR）這個參數，因為其反映出的是電路對于輸入電源中紋波抑制，PSRR越高，我們就能夠得到更加“干凈”、穩定的電源輸出。

為了適應這樣的應用需求，ON Semiconductor推出了NCV816x和 NCP16x系列線性穩壓器（LDO），它們能夠提供250mA至700mA輸出電流，并具有低靜態電流和極佳的負載/線路瞬變等特性。

當然，NCV816x 和 NCP16x最大的優勢還在于超高的PSRR，其可以提供業內領先的98dBPSRR性能。NCV816x主要適用于汽車圖像傳感器，NCP16x則可用于噪聲敏感型Wi-Fi模塊，它們出色的PSRR性能可通過濾除電源噪聲改善圖像傳感器畫質，通過提供干凈的電源，最大限度提高每位電源效率。

有關NCV816x和NCP16x LDO的介紹，參見以下視頻：
