Texas Instruments Voltage Reference TL431AIDRE4

The TL431AIDRE4 is a precision programmable voltage reference from Quarktwin Technology Ltd. It features an adjustable output voltage range from approximately 2.5 V to 36 V, allowing for flexibility in various applications. The device is characterized by a low output impedance of 0.2 Oc and a sink current capability ranging from 1 mA to 100 mA. It offers three grades of initial accuracy at 25¬8C: 0.5% for B grade, 1% for A grade, and 2% for standard grade. The TL431AIDRE4 operates effectively across a wide temperature range of -40¬8C to 125¬8C, ensuring stability in diverse environments. This voltage reference is suitable for applications such as adjustable voltage and current referencing, secondary side regulation in flyback switch-mode power supplies, and as a replacement for Zener diodes.
