TL431/TL431A Programmable Shunt Regulator
Features Description
• Programmable Output Voltage to 36 Volts The TL431/TL431A are three-terminal adjustable regulator • Low Dynamic Output Impedance 0.2Ω Typical series with a guaranteed thermal stability over applicable • Sink Current Capability of 1.0 to 100mA temperature ranges. The output voltage may be set to any • Equivalent Full-Range Temperature Coefficient of value between VREF (approximately 2.5 volts) and 36 volts 50ppm/°C Typical with two external resistors These devices have a typical • Temperature Compensated For Operation Over Full Rated dynamic output impedance of 0.2Ω. Active output circuitry Operating Temperature Range provides a very sharp turn-on characteristic, making these • Low Output Noise Voltage devices excel lent replacement for zener diodes in many • Fast Turn-on Response applications.
