NCV59301DS28R4G is a low-voltage, low-power consumption, adjustable, three-terminal series shunt-mode linear regulator, part of STMicroelectronics\' NCV series of voltage regulators. As with most device defined by their category, NCV59301DS28R4G is primarily used for its voltage regulation functionality, featuring a high power supply rejection ratio (PSRR) to eliminate unwanted noise from an energy source.

This device can be used either as a negative-voltage or a positive-voltage regulator. It features a wide adjustable output and a low ground pin current, as well as a thermal protection function. It includes a built-in precision reference voltage source and temperature-compensated current source for stability.

NCV59301DS28R4G can be used in a wide range of applications including, but not limited to personal computers, consumer and industrial equipment, automotive, telecom and datacom, portable and battery powered devices, graphics cards and power supplies. Specifically, the device may be employed as a set and reset flip-flop operating voltage regulator, voltage reference and current source, gate drive circuit and power drivers, in addition to its primary role as a voltage regulator.

NCV59301DS28R4G operates by utilizing an input voltage, which is then filtered by an internal filter to provide sufficient noise suppression by eliminating unwanted signal transients. The filtered voltage is compared to a reference voltage. If the voltage is higher than the reference, the output is amplified down to the desired voltage. Similarly, if the voltage is too low, it is amplified to the desired level.

Ripple rejection is one of the key features of this device, due to its high PSRR of 70-80dB which helps the regulator maintain stability and reduce unwanted high frequency noise from the energy source. This high performance is maintained with the help of an internal filter that provides a high level of noise suppression. The device also features a wide adjustable voltage range, and can output up to a maximum of 28V.

The device itself is made using STMicroelectronics\' advanced 0.18-lim high voltage process based on advanced NMOS and PMOS technologies, enabling low power consumption and a wide operating temperature range. It also comes in a compact SOT-223 package, providing a more efficient space saving integrative system. The package contains an ESD jacket that protects the device from Electro-Static Discharge and vibration, allowing for a more reliable product life cycle.

To conclude, the NCV59301DS28R4G is a low-voltage, low-power consumption, adjustable, three-terminal series shunt-mode linear regulator from STMicroelectronics\' NCV series. It is typically used as an adjustable voltage regulator, providing a stable and reliable output with high PSRR and ripple rejection, along with a wide adjustable voltage range and a thermal protection function. Its advanced 0.18-lim high voltage process technology ensures low power consumption and operational reliability, and its SOT-223 package ensures integrative system efficiency.
