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.

Features

  • Average temperature coefficient 50 ppm/°C
  • Temperature compensated for operation over the full temperature range
  • Programmable output voltage
  • Fast turn-on response
  • Low output noise
  • LM431 in micro SMD package
  • See AN-1112 for micro SMD considerations
