The TL431ATA by HTC is a three-terminal adjustable shunt regulator designed for precision voltage regulation applications. It features a programmable output voltage capability, allowing users to set the output to any value between approximately 2.5V and 40V using two external resistors. This device boasts a guaranteed 0.5% reference voltage tolerance, ensuring high accuracy in its operation.
With a low typical dynamic output impedance of 0.2Ω, the TL431ATA provides stable regulation. It operates over a wide temperature range of -40℃ to +125℃ and has a low output noise voltage and fast turn-on response, making it an excellent replacement for zener diodes in various circuits.
The TL431ATA is available in multiple package types, including TO-92, SOT-23 3L, and SOT-89 3L, catering to different design requirements for board space and thermal management. Its applications include shunt regulation, precision high-current series regulation, crowbar circuits, and voltage monitoring.
Key electrical characteristics include a cathode current range of -100mA to 150mA and a reference input current range of -0.05mA to 10mA. The device is temperature compensated for stable operation across its specified temperature range.
The reference voltage is approximately 2.5V with a guaranteed 0.5% tolerance for TL431C/A variants.
The output voltage can be programmed up to 40V.
The operating temperature range is -40°C to 125°C.
The device is available in a TO-220 through-hole package.
The continuous cathode current range is -100 mA to 150 mA.
The typical full range temperature coefficient is 50 PPM/°C.
