Linear voltage regulators are one of the most common types of PMIC, which are used to provide a precisely regulated voltage output for micro-electronic circuits. The NCP110AFCT110T2G is a very popular linear voltage regulator, which features a voltage-in range of 2.7 to 6.5V, an output current of up to 100mA, and a maximum output voltage of 2.85V. It is an ideal choice for applications that require a low-noise low-dropout voltage supply.

NCP110AFCT110T2G Application Fields

The NCP110AFCT110T2G voltage regulator is used in a wide range of applications, such as cell phones, digital cameras, laptop computers, and various audio/video equipment. It is also a good choice for applications where a small dropout voltage and very low noise are required, such as portable instrumentation and medical devices. In addition, the NCP110AFCT110T2G is widely used in automotive electronics, including cruise control, navigation systems, and car audio systems.

Working Principle of NCP110AFCT110T2G Linear Voltage Regulator

The NCP110AFCT110T2G is a three-terminal, fixed voltage regulator that operates from a single supply of 2.7 to 6.5V. The output voltage is regulated at 2.85V, with a tolerance of ±2%. It is designed to provide very low noise and low-dropout voltage regulation. The NCP110AFCT110T2G regulator features built-in thermal shutdown and overcurrent protection, and it is designed to operate with a maximum power dissipation of 500mW.

At its core, the NCP110AFCT110T2G linear voltage regulator works by using an internal voltage reference source (VR) to compare the actual output voltage (VOUT) with an internal reference. A comparison is made between the two voltages with an error amplifier, and the output from this amplifier is used to drive an internal transistor (Q1). This transistor is connected in series between the input and output, and is connected such that it maintains the desired output voltage. When the input voltage exceeds the reference voltage, the transistor is turned on and allows current to flow from the input to the output. This decreases the output voltage, which reduces the current flow and maintains the desired output voltage.

One of the main advantages of the NCP110AFCT110T2G is its low noise, which is due to its low dropout voltage. The dropout voltage is the difference between the input voltage and the output voltage when the regulator is enabled. The NCP110AFCT110T2G has a relatively low dropout voltage of 0.85V, which means that it can operate reliably with a very small difference between the output and the input voltage. This low dropout voltage also helps to minimize power losses and therefore improve the efficiency of the device.

Conclusion

The NCP110AFCT110T2G linear voltage regulator is a very reliable and popular voltage regulator for a wide range of applications. It has a wide input range of 2.7 to 6.5V, an output voltage of 2.85V with a tolerance of ±2%, and very low noise and low-dropout voltage. In addition, the NCP110AFCT110T2G offers protection against thermal overload and overcurrent protection. It is an ideal choice for applications that require a precise and low-noise voltage supply.
