Overview

Product details

XB431-TL is a low voltage three-terminal adjustable voltage reference source launched by XINLUDA. The output voltage of this product can be set to any value between VREF (1.24V) and 6V by two external resistors. The operating voltage (1.24V) of this product is lower than the widely used XB431 shunt regulator. When used with an optocoupler, the XB431 device is an ideal voltage reference source in the isolated feedback circuit of a 3V~3.3V switching power supply. The typical output impedance of this product is 0.25Ω. Its active output circuit provides a very fast turn-on characteristic, making it suitable for many applications.
