The 100 mA output current drives optocoupler LEDs in feedback loops or biases small loads in industrial power supplies. ## Active lifecycle — no last-time-buy clock ticking That means STMicroelectronics continues to manufacture it with no announced end-of-life. ROHS3 compliance keeps it clear of the RoHS exemption deadlines.","metaTitle":"TL431AIZ-AP STMicroelectronics Shunt Voltage Reference","metaDescription":"TL431AIZ-AP adjustable shunt reference, ±1% tolerance, 100 mA output, -40°C to 105°C, TO-92-3.
