onsemi Voltage Reference TL431AIPG

The TL431AIPG is a programmable shunt voltage reference integrated circuit from Quarktwin Technology Ltd. It operates as a low temperature coefficient zener diode, providing an adjustable output voltage from 2.5 V to 36 V using two external resistors. The device supports a wide cathode current range of 1.0 mA to 100 mA, with a typical dynamic impedance of 0.22 ohms, making it suitable for applications such as digital voltmeters and power supplies. The voltage reference tolerance is ¬±0.4% at 25¬8C for the TL431B variant. It features a low output noise voltage and is temperature compensated for operation across its full rated temperature range. The TL431AIPG is also AEC-Q100 qualified, making it suitable for automotive applications. The device is available in a Pb-free, halogen-free package and complies with RoHS standards.
