LM431B Adjustable/2.5 V, 1% Tolerance Shunt Regulator Product Overview
●The LM431A / LM431B / LM431C are three terminal output adjustable regulators with thermal stability over the full operating temperature range. The output voltage can be set to any value between V-REF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications.
●Features:
■Programmable output voltage to 36 V
■Low dynamic output impedance 0.2 Ω (Typical)
■Sink current capability of 1.0 to 100 mA
■Equivalent full-range temperature coefficient of 50 ppm/°C (Typical)
■Temperature compensated for operation over full rated operating temperature range
■Low output noise voltage
■Fast turn-on response
