TL431/H431--电压基准，耐压36V，精度0.5%

The H431 series ICs are three-terminal adjustable shuntregulators with guaranteed thermal stability over a full operationrange. These ICs feature very sharp turn-on characteristics, lowtemperature coefficient and low output impedance, which make themideal substitutes for Zener diodes in applications such asswitching power supply, charger, and other adjustable regulators.The H431 is especially suitable for industry applications types.  The H431 precision reference is offered in band- gaptolerance: : 0.3%-1%. The H431 are characterized for operation from40°C to 125°C
