LM431AIM3/NOPB +BOM

Precision shunt regulator

LM431AIM3/NOPB General Description

The LM431AIM3/NOPB is a 3-terminal adjustable shunt regulator that guarantees temperature stability across its entire operating range, providing reliability and consistency in various environmental conditions. Its adjustable output voltage, settable with external resistors, adds a level of customization and adaptability to suit specific application requirements. Furthermore, its sharp turnon characteristics make it a valuable replacement for numerous Zener diode applications, broadening its usage and versatility. Available in space-saving SOIC-8, SOT-23, and TO-92 packages, the LM431AIM3/NOPB offers practicality and convenience in design and layout considerations
