Rochester Electronics PMIC - Voltage Reference TL431ILPG

The TL431ILPG is a programmable shunt voltage reference from Lingto Electronic Limited, designed for applications requiring precise voltage regulation. It operates with a reference voltage of 2.5 V and can be programmed to output voltages ranging from Vref to 36 V using two external resistors. The device supports a wide cathode current range of 1.0 mA to 100 mA, with a low dynamic output impedance of 0.22 ohms, making it suitable for replacing traditional zener diodes in various applications such as power supplies and op-amp circuitry. The TL431ILPG features a voltage reference tolerance of ¬±0.4% at 25¬8C, and it is temperature compensated for operation across a full rated temperature range of -40¬8C to 125¬8C. It is also AEC-Q100 qualified, making it suitable for automotive applications. The device is available in a TO-92 package and is compliant with RoHS standards, ensuring it is free from lead and halogens. This combination of features makes the TL431ILPG a reliable choice for engineers seeking a versatile voltage reference solution.
