Description générale
The ET431B / ET432B device is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable industry and automotive temperature range. The output voltage can be set to any value between VREF(Typical 2.495 V) and 36 V with two external resistors. These high performances make it very suitable for multiple applications, such as onboard regulation, adjustable power supplies, and switching power supplies. The ET431B / ET432B devices are offered in two grades, with initial tolerances (at 25 °C) of 0.5%, for the B grade, respectively. In addition, low output drift versus temperature ensures good stability over the entire temperature range. ET431B / ET432B is specified for the wide operating temperature range of -40 to +125 °C.
