TL431BQDR TI Voltage Reference
The TL431B is a precision programmable shunt reference with 0.5% initial tolerance. It operates over a current range of 1mA to 100mA and provides an adjustable output voltage from 2.495V to 36V using two external resistors. The device features a typical temperature drift of 0.7 mV/°C and low output impedance. Selection is the industry standard for voltage references and error amplifiers. Applications include isolated feedback loops in switching power supplies (via optocoupler), precision voltage monitoring circuits, adjustable linear regulators, and constant-current sinks for LED drivers.
