Shunt Voltage Regulator IC; Termination Type:SMD; Package/Case:3-SOT-23; No. of Pins:3; Operating Temperature Range:0°C to +70°C; Leaded Process Compatible:No; Peak Reflow Compatible (260 C):No; Current Rating:15A ;RoHS Compliant: No

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.
