Product Summary
The LM431AIM3/NOPB 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 Nationals micro SMD package technology. The output voltage of the LM431AIM3/NOPB 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 LM431AIM3/NOPB is an excellent replacement for many zener diode applications.
