4.4 SMPS PROGRAMMABLE SHUNT REGULATOR (FAIRCHIELD TL 431)
Features · Programmable output voltage to 36 volts · Low dynamic output impedance 0.20 typical · Sink current capability of 1.0 to 100 mA · Equivalent full-range temperature coefficient of 50 ppm o C typical · Temperature compensated for operation over full rated operating temperature range · Low output noise voltage · Fast turn-on response
Description The TL 431/TL 431A are three-terminal adjustable regulator series with a guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 2.0W Active output circuity provides a very sharp turn-on characteristic making these devices excel lent replacement for zener diodes in many applications
