RT9093/RT9093A/RT9093N 是一款低壓差線性穩壓器(LDO),可在 1.2V 至 5.5V 的輸入電壓範圍內運作,並提供最高 300mA 的輸出電流。其輸出電壓支援兩種模式以滿足不同應用需求。在可調模式下,輸出電壓可設定於 0.8V 至 5V 之間;在固定輸出模式下,則可提供 0.8V 至 3.45V 的固定輸出電壓,無需外接電阻分壓器,有助於降低物料成本(BOM)並節省 PCB 空間。該元件內建 EN 使能腳位,可用於系統電源時序控制,同時整合過電流保護(OCP)及過溫保護(OTP),以防止異常狀況發生。RT9093/RT9093A/RT9093N 提供 TSOT-23-5 封裝,支援固定輸出及可調輸出版本,方便各種應用設計;另提供無需外接分壓電阻的 ZQFN-4L 1mm × 1mm 封裝版本。該產品完整規格適用於接面溫度 TJ = -40°C 至 125°C 的工作範圍。
