The TL431ASF by HTC is a three-terminal adjustable shunt regulator designed for precision voltage regulation applications. It allows for a programmable output voltage up to 40V, controlled by two external resistors. The device boasts a guaranteed reference voltage tolerance of 0.5% and a typical dynamic output impedance of 0.2 Ohms, making it a superior replacement for zener diodes.
This shunt regulator operates over a wide temperature range of -40°C to 125°C, ensuring stable performance in various environments. Key features include temperature compensation for operation over the full rated temperature range, low output noise voltage, and fast turn-on response. The TL431ASF is available in a compact SOT-23-3 surface-mount package, suitable for space-constrained designs.
Applications for the TL431ASF include precision high-current series regulators, crowbar circuits, PWM converters with reference, voltage monitors, and precision current limiters. Its active output circuitry provides a sharp turn-on characteristic, enhancing its utility in demanding electronic circuits.
