電圧リファレンス、プログラムブル精度、シャント・レギュレータ

Favorite

Overview

集積回路TL431、A、Bは、3端子プログラムブル・シャント・レギュレータ・ダイオードです。このモノリシックIC電圧リファレンス外部抵抗器2つによってVref~36 Vでプログラム可能な低温度係数ツェナーとして動作します。動作電流範囲は1.0 mA~100 mAと広く、定格動的インピーダンスは0.22 Wです。このリファレンスの特性は、デジタル電圧メータ、電源、オペアンプ回路など多くのアプリケーションで、ツェナー・ダイオードの優れた代替となります。2.5 Vのリファレンスは、5.0 Vのロジック電源から安定したリファレンスを得られるので便利です。TL431、A、B はシャント・レギュレータとして動作するため、正負いずれかの電圧リファレンスとして使用できます。

  • Programmable Output Voltage to 36 V
