FAQs

What is LMV431BIMF?

The LMV431BIMF is a precision adjustable shunt voltage reference integrated circuit manufactured by Texas Instruments. It is commonly used in various electronic circuits as a voltage reference to provide a stable and accurate reference voltage for applications such as power supplies, amplifiers, and voltage regulators.

How Does LMV431BIMF Work?

The LMV431BIMF works by comparing the input voltage to its internal reference voltage and then regulating the output voltage to maintain a constant value. It operates as a shunt regulator, shunting excess current to maintain the desired output voltage. The reference voltage can be adjusted through external resistors, offering flexibility in setting the output voltage.

How Many Pins does LMV431BIMF have and What are the Functions of the Pinout Configuration?

The LMV431BIMF is available in a SOT-23-5 package with 5 pins. The pinout configuration includes:

  • Cathode (K): Connection to the load or ground.
  • Anode (A): Connection to the input voltage.
  • Adjust (ADJ): External adjustment pin for setting the output voltage.
  • Reference (REF): Output pin for the stable reference voltage.
  • Ground (GND): Ground reference for the IC.

What are the Pros and Cons of LMV431BIMF?
