概述

Description

NCV431BVDR2G is an automotive-grade, adjustable shunt voltage reference from ON Semiconductor. It functions like a programmable Zener (TL431 family): an external resistor divider sets the output reference, and the device sinks current to regulate the voltage at about 2.495 V (Vref) with high accuracy over temperature.
Key points:
- Type: three-terminal precision shunt regulator (voltage reference).
- Reference: typically around 2.495 V; external resistor network programs the regulated output.
- Configuration: used in feedback/regulation loops, DC-DC controllers, voltage sensing, and reference applications.
- Features: low dynamic impedance, suitable for automotive temperature ranges; RoHS-compliant.
- Package: three-pin, surface-mount (SOT-23/SC-70 family variants common; “VDR2G” denotes RoHS lead-free packaging).
Pinout (typical): Ref, Anode, Cathode (three pins).
Applications: power supplies, voltage regulation circuitry, battery charging, and protection circuits requiring a stable reference.

Package

NCV431BVDR2G is in a 3‑lead SOT‑23 (SC‑70‑3) surface‑mount package. RoHS compliant, lead‑free with tape‑and‑reel packaging.

Pinout

- Pin count: 3 pins (SOT-23 package, R2G).
- Function: Precision adjustable shunt regulator (TL431-equivalent) with ~2.495 V reference. Used to regulate voltage by shunting current; pins are typically Reference (R), Anode (A), and Cathode (K).

Manufacturer

Manufacturer: ON Semiconductor (ONsemi).
What kind of company: A global semiconductor company that designs and manufactures electronic components and integrated circuits, including analog, power management, sensors, and other devices for automotive, industrial, and consumer electronics.
