RP123 系列
低噪音和低消费电流 250mA LDO稳压器

  • 概述

    The RP123 is a LDO regulator that provides low output noise, high ripple rejection and fast response characteristics, achieved by low supply current. This device is suitable not only for noise-sensitive applications such as high-performance analog circuits, but also for various applications.

    Key Benefits

    • Achieves Low Noise, High PSRR and Fast Response.
    • Provides Saving Space by Adopting of Small Package without Noise Bypass Capacitor.
    • Provides Long-Duration of Operation for Battery-powered Equipment by Low Supply Current of 9.5 µA (Typ.), despite the low-noise LDO.
