NCP114 is a low dropout voltage regulator built in a space-saving compact SOT-23-5L package and having a maximum output current of 280mA. Its wide operating input voltage range of 0.9V to 22V is ideal for applications requiring low voltage regulated power output. The NCP114ASN280T1G is a single output device with an adjustable output voltage. It has a guaranteed output current of 280mA and can provide a 160mV dropout voltage at full load. In addition, its wide operating temperature range of -40°C to +85°C ensures reliable operation in even the most challenging environments.

The NCP114ASN280T1G is ideal for use in many battery-powered applications such as portable handsets, personal digital assistants (PDAs), and notebooks. It is also suitable for general low voltage power regulation in consumer and computing systems, gaming consoles, graphics cards, and other systems where space is limited and only a single power supply output is required. In addition, this linear voltage regulator can be used as an aids control in intelligent systems, such as different types of motor controllers.

Working Principle

The NCP114ASN280T1G operates in a linear voltage regulator mode wherein the output voltage is set to a predetermined value by monitoring the voltage at the output terminal with the help of a feedback network. When the output voltage starts to drop, the error amplifier senses the actual output voltage of the regulator and generates an error voltage that is fed to the pass element of the regulator. This feedback voltage is then compared with the reference to determine whether or not the output voltage should be increased or decreased. The pass element, which is usually implemented as an NPN power transistor, allows current to flow through the regulator in order to ensure that the output voltage remains at the desired level. Additionally, the device also features a thermal shutdown system that helps protect the regulator from damage due to excessive operating temperature.

The NCP114ASN280T1G is also designed for low quiescent current and low ripple operation. This makes it suitable for applications where power efficiency and output noise are important considerations. Additionally, it has a low dropout voltage, which allows the device to regulate voltages as low as 0.9 V.

Conclusion

The NCP114ASN280T1G is an excellent single output device suitable for a wide range of applications. Its low dropout voltage, wide operating temperature range and low ripple operation make it an ideal choice for low voltage regulated power. Additionally, its space-saving design makes it suitable for applications where space is at a premium and only a single power output is required.
