  RE: Using adjustable LM4041 shunt voltage reference instead of LM431

  Hi, Thank you very much for a quick reply. LM4041 is an attractive shunt voltage reference, because it has a low minimum operating current 65 uA. In the case, when the input voltage is a battery, it is important to have over-voltage protection...

  LM431: LM431

  TI Thinks Resolved

  Part Number: LM431 Hello I am using the LM431, works well at 14V, I get a 1 volt difference between Vin and Vo with Iz less than 5 mA, everything is ok BUT, at 28V, impossible to goi down 50 mA for Iz ( I am still in the spec ) but the LM431 heats...

  LM431: Vref regulation voltage 2.6V instead of 2.5V

  TI Thinks Resolved

  Part Number: LM431 Hello, I am using the LM431BIM3 in the control loop of a flyback converter. However instead of having a Vref of 2.5V, i am measuring 2.6V instead which makes my output regulates at 12.6V instead of 12V. R2=4.7k, R1=18k, R3=2.2k...

  RE: LMV431A: Anode to cathode voltage(VCA) in comparator mode operation

  HI Basil, We do not. The main difference between the LM431 and LMV431 is the VKA when VREF > 1.24V/2.495V. For the LM431, When VREF > 2.495V the VKA = ~2V as the app note shows. For the LMV431, When VREF > 1.24V the VKA = ~1V. This is the...
