Overview

LP2950/LP2951はマイクロパワー低ドロップアウト (LDO) リニア電圧レギュレータで、入出力電圧差動が極度に低くても適正なレギュレーションを維持することに特化して設計されています。静止バイアス電流が75 µAと非常に低いのが特長であり、100 mAを超える出力電流を供給できます。内部電流/温度制限による保護がされています。リニア電圧レギュレータ LP2951 LDO には 3 つの追加機能があります。1 つ目はエラーバー出力です。外部回路にレギュレーション外状態の信号を送出するのに、またはマイクロプロセッサのパワーオンリセットとして使用できます。2 つ目は、出力電圧を 5.0 V/3.3 V/3.0 V 出力 (バージョンによる) にプリセットしたり 1.25 V ～ 29 V でプログラムしたりできる機能です。ピンアウト抵抗ディバイダと、エラーアンプ・フィードバック入力への直接アクセスで構成されます。3 つ目の機能はシャットダウン入力です。ロジックレベル信号により、レギュレータ出力のターンオフ/ターンオンができます。入出力電圧差動とバイアス電流が低い仕様のため、有用なバッテリ寿命の延長が望まれるバッテリ駆動コンピュータや消費者向け/産業用機器に最適です。LP2950は 3 ピン・ケース 29/DPAK パッケージで提供され、LP2951 は 8 ピン・デュアルインライン SO-8/Micro-8 表面実装パッケージで提供されます。サフィックス「A」が付いたものは初期出力電圧耐性 +/-0.5% です。
