In general, these linear voltage regulators require few external components and are easy to implement, reducing system cost and complexity while providing a superior level of flexibility.

Applications of NCP120BMX120TCG

NCP120BMX120TCG voltage regulators are suitable for virtually any voltage-regulation task. They are widely used in automotive applications, such as powertrain, infotainment, and driver assistance systems, as well as in consumer electronics, industrial automation, and robotics. They are designed to provide clean, low-noise power for safe and reliable operation of sensitive microcontroller-based systems and other low-power digital logic. Some common applications of these voltage regulators are:

• Power supply and voltage regulation for embedded control systems
• DC-DC conversion between high and low voltages
• Battery charging

• Noise reduction for digital logic circuits
• Vehicle-battery-powered applications

Working Principle of NCP120BMX120TCG

NCP120BMX120TCG linear voltage regulators work according to an internal "Regulated Voltage Control" principle. This principle is based on a control loop circuit, which consists of an error amplifier, a voltage reference, current sense, and output transistor. It operates at a constant frequency to closely monitor and regulate the output voltage to the prescribed value. The error amplifier senses the load current variation to maintain the output voltage regulation by varying the control voltage on the output transistor. It allows for quick response to line and load transient, which makes it ideal for applications that require dynamic power supply regulation.

The NCP120BMX120TCG provides significantly lower input voltage requirements and a wide adjustable output range. They include an adjustable current limit to protect against an overload condition, and they offer undervoltage and overvoltage lockout to protect against an output voltage that goes outside the range of the regulator. The device also provides thermal shutdown protection and internal EMC filter for high noise immunity.

Conclusion

NCP120BMX120TCG linear voltage regulators are widely used for voltage regulation in sensitive logic and embedded control systems, as well as for battery charging and DC-DC conversion. They provide excellent line and load transient response and robust overload protection, making them ideal for a variety of application. In addition, they require few external components, making them easy to implement and reducing system cost and complexity.
