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
  • Voltage Reference Tolerance: +/- 0.4%, Typ @ 25°C (TL431B)
  • Low Dynamic Output Impedance, 0.22 W Typical
  • Sink Current Capability of 1.0 mA to 100 mA
  • Equivalent Full-Range Temperature Coefficient of 50 ppm/ °C Typical
  • Temperature Compensated for Operation over Full Rated Operating Temperature Range
  • Low Output Noise Voltage
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
