The LMV431CM5/NOPB by National is a low-voltage, adjustable precision shunt regulator. It provides a stable 1.24V reference voltage that can be adjusted up to 30V using an external voltage divider. This device is designed for applications requiring zener diode-like performance at low voltages.
Key electrical specifications include an initial accuracy of 1.5% maximum, a minimum regulation current of 80µA, and a low operating current of 55µA. The operating temperature range is -40°C to 85°C, making it suitable for industrial environments. The device also boasts a low output impedance of 0.25Ω and a fast turn-on response.
Available in SOT-23 and TO-92 packages, the LMV431CM5/NOPB supports both surface mount and through-hole mounting types. Its design allows for negative feedback from the cathode to the adjust pin to control the cathode voltage, similar to a non-inverting op-amp configuration.
This shunt regulator is functionally suited for applications such as low drop-out regulators and battery management systems where precise voltage referencing is critical. Its low cost and versatile adjustability make it a practical choice for designers.
