Overview

MC33761 は、低ドロップアウト (LDO) スイッチング電圧レギュレータで、優れたノイズ性能を備えています。革新的な設計により、この回路は外部のバイパス・キャパシタがなくても優れた 40uVRMS ノイズ・レベルに達します。この LDO は、小型 SOT23-5 的パッケージで提供され、スペースの節約や低ノイズを最優先する設計に最適な選択肢です。外部のバンドギャップ・キャパシタがないため、ウェイクアップ信号への応答時間が早くなり、40us (反復モードで) 以内をキープするため、MC33761 はポータブル・アプリケーションに最適です。また MC33761 低ドロップアウト (LDO) リニア電圧レギュレータは、どんなバースティング・システムにも見られる高速過渡バースト発生時に過剰なアンダーシュートを示す新しいアーキテクチャもホストします。最後に、-75dB よりも良い値のスタティック・ライン・レギュレーションで、必然的にダウンストリーム電子機器を不安定なラインから保護します。
