LM431AIZ/LFT1 Product Details

LM431AIZ/LFT1 Overview


The reference voltage makes use of a handy TO-226-3, TO-92-3 (TO-226AA) (Formed Leads) package.This program utilizes the handy Shunt package.The reference voltage is enclosed in the Tape & Reel (TR) external packaging.3 terminations with various functions.±2.2% tolerance for precise voltage reference.TWO TERMINAL VOLTAGE REFERENCE analog IC is coupled with the reference voltage.It outputs 37V voltage according to the test statistics.It is sufficient to generate 1 outputs. It can handle Adjustable output (s).3 pins are settled in the voltage reference ic.Through Hole is available for demanding PCB design.Qualified to work within -40°C~85°C TA.Other relevant parts can be found by searching "LM431".It is suitable for 100mA input applications.It is appropriate for Through Hole applications.You cannot expect output current higher greater than 100mA from the reference voltage.As per the datasheet, the voltage reference ic can output 37V voltage at its maximum.Generally, 1mA is what its cathode current should be.Since the max input voltage of the part is 37V, users ought to confine the voltage correspondingly.A minimum voltage of 2.44V is required to supply it.A fixed/minimum voltage of 2.495V is generated.
