SPX431AM1-L/TR

参考电压 20V 150mA temp 0C to 105C Precision Adjustable Shunt Regulator

GENERAL DESCRIPTION  

The SPX431AM1-L/TR SPX431A is a three-terminal adjustable  shunt voltage regulator providing a highly  accurate bandgap reference.

The SPX431A acts as an open-loop error  amplifier with a 2.5V temperature  compensation reference. The SPX431A has  thermal stability, wide operating current of  150mA and broad temperature range of -40°C  to 125°C, making it suitable for a variety of  applications which require a low-cost, high  performance solution. The SPX431A tolerance  of 0.5% is proven to be sufficient to overcome  all other errors in the system to virtually  eliminate the need for trimming in the power  supply manufacturer's assembly line and  contribute a significant cost savings. The  output voltage may be adjusted to any value  between VREF and 36 volts with two external  resistors.
