The NCV47701PDAJR2G is a voltage regulator from the Linear PMIC (Power Management ICs) family. It is an adjustable LDO (low dropout) linear regulator, designed to provide up to 1.5A of output current. It maintains a low dropout voltage, excellent load and line regulation, and has a built-in thermal shut-down and current limit protection. It is rated for a maximum input voltage of 36V, and can be adjusted to output a wide range of voltage levels.

The NCV47701PDAJR2G linear regulator is best suited for applications that require a reliable, low-dropout, adjustable voltage supply. It is ideal for systems with multiple supplies, where it can be used to supply odd line voltages or any combination of output voltages.It can also be used to support high power applications with large input voltage variations, or to reduce the number of components in a power supply design. Its high load and line regulation, along with its low dropout voltage, make the NCV47701PDAJR2G the perfect choice for many applications.

The internal operation of the NCV47701PDAJR2G is fairly straightforward. When the input voltage is applied, a differential amplifier senses the voltage across two reference resistors, one of which is adjustable, and outputs a voltage proportional to the voltage difference. This voltage is compared to the output voltage, and any discrepancy is adjusted by controlling a pass transistor. The pass transistor is used to regulate the output voltage by varying the amount of current that flows through the load.

The NCV47701PDAJR2G provides built-in thermal shutdown and current limit protection. Thermal shutdown activates if the die temperature exceeds the preset thermal limit. When this happens, the output is disconnected from the input, and the regulator is disabled. The current limit protection ensures that the output current never exceeds 1.5A, protecting the device and the load, as well as preventing thermal damage.

In addition to its adjustable output voltage, the NCV47701PDAJR2G offers several other features to enhance system performance, including soft-start and short-circuit protection. Soft-start helps prevent excess inrush current during start-up, and short-circuit protection safely reduces the output current when an output short occurs. These features, combined with its ultra-low dropout voltage and adjustable voltage output, make the NCV47701PDAJR2G an ideal power solution for many different applications.
