Precision Programmable Reference Integrated Circuit IC
The SGM431x is a precision programmable shuntvoltage reference that
can be used in manyapplications. It is a three-terminal
adjustable-outputdevice that can keep stable under all capacitive
loads.It requires two external resistors in application to set
theoutput voltage is to any value between VREF and 36V.All versions
have a maximum operating current of100mA.The SGM431x features low
dynamic impedance, lownoise, and low temperature coefficient to
ensure astable output voltage over a wide range of
operatingtemperatures and currents. These high performancesmake it
very suitable for multiple applications, such asprecision audio
components and flyback switchingpower supplies.The SGM431 is
available in Green SOIC-8, SOT-23,SOT-89-3, SOT-23-5 and SC70-6
packages. TheSGM431B is available in Green SOIC-8, SOT-23,SOT-89-3
and SOT-23-5 packages
