UTC 智能電錶 Smart Meter應用

智能電錶對穩定供電與長期精準監測的要求極高，UTC 提供一系列專為電錶電源管理與訊號處理打造的高可靠度解決方案。
從 低靜態電流 LDO、電壓穩壓器 到 線性穩壓 IC，每款產品都經過嚴選，兼顧低功耗、高效率與長期穩定運作。

低功耗電源核心：Low IQ LDO 系列
UR56XX、UR75XX、UR76XX 與 LR9282G-33 等多款 LDO 具備極低靜態電流（1~5μA）與寬輸入電壓範圍，非常適合電池供電與長期待機的電錶應用。
在 智慧計量模組、RTC 電源維持 或 感測電路穩壓 等環節，皆能提供高效率且穩定的電壓輸出。

高可靠穩壓方案：Voltage / Linear Regulator 系列
從 LR1106、LR1801 到 LM317M、78L05 系列，支援 30~40V 輸入電壓與高達 1A 輸出能力，並具備 高 PSRR 抗雜訊表現（60~80dB），確保量測資料穩定不失真。
這些器件適用於 MCU 主電源、通訊模組電壓穩定 及 感測放大電路供電，在嚴苛環境下依然維持一致輸出。
