The NCV5661DT12RKG is a series of linear voltage regulators that make up a subset of the wider family of PMIC (Power Management Integrated Circuits). These devices offer low dropout voltage operation, flexibility and high system efficiency, making them suited to a wide variety of applications.

Linear regulators are DC-to-DC devices that are most often used to regulate a single output voltage from a DC source. The NCV5661DT12RKG series of devices take this to the next level by providing a range of voltage and current levels and flexibility to accommodate various load requirements. This is done by various internal components such as an adjustable reference voltage and current-limiting circuitry.

The main feature of the NCV5661DT12RKG is an adjustable output voltage that can range from 0.5 to 36V. The high output current that the device can supply is 6A. Low noise and high ripple rejection (over 80dB) are also highlights to be noted. The device operates over the industrial temperature range of -40°C to +125°C, has low on-resistance of 900 mΩ, and provides good line and load transient specs.

Aside from the basic parameters listed above, the NCV5661DT12RKG also provides a number of features designed to meet the specific needs of various application areas. This includes undervoltage lockouts (UVLO), short-circuit protection (SCP), and thermal shutdown (TSD). These built-in features make it suitable for a wide range of system designs.

The NCV5661DT12RKG are commonly used in a range of consumer, industrial, and medical applications. This includes consumer devices such as appliances, handheld devices, and guidance systems, as well as sophisticated medical and communication devices. Industrial applications can include motor drives, power supplies, robotics and automated test equipment (ATE). For these application areas, the electrical and thermal properties of the device provide the necessary performance and reliability.

The principle of operation of linear regulators is quite simple. The device uses a combination of resistors and transistors that are placed in series and parallel to help regulate the output voltage to the desired level. Through sense and feedback, the device is able to continuously regulate the output voltage with respect to the reference voltage at the input. The main control is provided by the collector-emitter voltage of the series transistor, which adjusts itself based to the reference voltage, making sure the output voltage is pegged to the required level.

The NCV5661DT12RKG series of linear voltage regulators gives designers tremendous flexibility, with adjustable output voltage and range of features designed to accommodate a wide range of applications. Its low noise, high ripple rejection and extremely low on-resistance give it the capability to meet the stringent requirements of many applications, while its built-in features provide improved safety and reliability.
