The TL431BQPK from Texas Instruments is a three-terminal adjustable shunt regulator designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors, making it highly versatile for applications requiring adjustable voltage references.
This device boasts a typical output impedance of 0.2Ω and a sink current capability ranging from 1mA to 100mA. The B grade offers a reference voltage tolerance of 0.5% at 25°C. It operates reliably within a temperature range of -40°C to 125°C.
The TL431BQPK is housed in a SOT-89 package, suitable for surface mounting. Its active output circuitry ensures a sharp turn-on characteristic, positioning it as an effective replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies.
