LM431AIM3 Datasheet

Adjustable Precision Zener Shunt Regulator


The LM431AIM3 is a 3-terminal adjustable shunt regulator with ensured temperature stability over the entire temperature range of operation. The output voltage may be set at any level greater than 2.5V (V REF ) 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. LM431AIM3 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
