このシリーズの高性能LDOレギュレータは、ノイズの影響を受けやすいアプリケーションやRFアプリケーション向けと考えられており、非常に優れた電源除去比特性(1 kHzにて最大92 dB)および超低ノイズ動作(6.3 µVRMSまで)によって、極めて感度の高い負荷に適したクリーンで安定した主力電圧を供給します。 高度な設計により、低消費電力で高速かつ安定した動的性能を保証します。

Ultra-low noise and low-consumption LDO for ultra-sensitive loads

The LDLN025 is a series of 250 mA low-dropout voltage regulators designed for noise sensitive loads. Able to work with an input voltage range from 1.5 to 5.5 V, it provides accurate and stable voltage (I’d refer to the single LDO rather than the family, otherwise it can be read as the LDO offer several voltages) to precision ADCs, VCOs, or sensors, in space-constrained products such as smartphones, smart watches, fitness monitors, medical sensors, and wireless IoT devices.

Due to its best-in-class output noise figures (<6.5 µVRMS) and very high PSRR (80 dB), the LDLN025 provides a very clean output, suitable for ultra-sensitive loads (If we have room I’d mention here the very small package as a strength point, rather than the ceramic caps). Moreover, its very low quiescent current, only 12 μA at no-load, extends the battery life of applications requiring very long standby time.
