Description
The TL431N3 series are three-terminal adjustable regulators with guaranteed thermal stability over
applicable temperature range. The output voltage may be set to any value between VREF (approximately
2.495 volts) and 36 volts with two external resistors. These devices have a typical dynamic output
impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making these
devices excellent replacement for zener diodes in many applications.
Features
• Programmable output voltage
• Temperature coefficient is 50ppm/°C typical
• Temperature compensated for operation over full temperature range
• Low output noise voltage
• Fast turn on response
• Pb-free package
