随着鹏芯科技在各种疑难芯片解密领域的重大突破，为我们在更多高难度解密领域的研究积累的丰富经验，这里我们提供对LM431BIMX芯片的基本性能特征介绍，供客户及工程师参考借鉴。更多解密请关注.
General Description
The LM431 is a 3-terminal adjustable shunt regulator with guaranteed temperature stability over the entire temperature range of operation. It is now available in a chip sized package (4-Bump micro SMD) using National’s micro SMD package technology. The output voltage may be set at any level greater than 2.5V (VREF) up to 36V merely by selecting two external resistors that act as a voltage divided network. Due to the sharp turn-on characteristics this device is an excellent replacement for many zener diode applications.
