... Fast Turn-on Response Internal Block Diagram © 2012 Fairchild Semiconductor Corporation LM431SA/LM431SB/LM431SC Rev. 1.0.9 Description The LM431SA/LM431SB/LM431SC are three terminal output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between V (approximately 2.5 volts) REF and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2Ω ...
