The S-873021CUP-AFET2G is a special purpose voltage regulator developed by （ON Semiconductor) for analog and mixed-signal applications. The device is a two-stage regulato, with each stage regulating the output +/-1% accuracy over a wide operating temperature range. The regulator uses a combination of an advanced design and an external FET, which enables the user to control all settings via an external, programmable control interface rather than through discrete components.

The S-873021CUP-AFET2G is designed for a wide range of applications, from power supplies, signal processing, and communications, to automotive, industrial and military systems. It is also suitable for a variety of analog and mixed-signal designs due to its wide operating temperature range, its excellent transient response, and its on-chip error amplifier and soft-start functions. Due to its external FET design, it offers the user the flexibility to easily adjust the voltage levels and other parameters to match the application.

The S-873021CUP-AFET2G utilizes an inductor-capacitor (LC) bridge circuit to regulate the voltage. The bridge circuit consists of four switching elements, two capacitors and two inductors, which are connected in a series-parallel fashion. The switching elements are controlled by the device\'s Programmable Digital Logic (PDL) core, which receives the user\'s settings and the input voltage information. Once the user has entered the desired settings for the regulator, the PDL core modulates the switching elements to maintain the desired output voltage with a minimum of distortion.

The S-873021CUP-AFET2G includes an on-chip error amplifier, soft-start circuit, current monitor, and adjustable reset circuit for maximum design flexibility. The error amplifier monitors the output voltage and compares it to a reference voltage. If the output voltage is not within the set accuracy level, the error amplifier generates a signal which is sent to the PDL core to adjust the switching elements until the output voltage reaches the desired level. The soft-start circuit prevents inrush current during the startup of the system by slowly ramping up the voltage over a fixed period of time. The current monitor monitors the current draw on the system and can be set to trip a protection circuit at a certain current level. The adjustable reset circuit sets a threshold at which the system will reset itself if the current draw exceeds a certain level.

The S-873021CUP-AFET2G is an ideal solution for a variety of applications including automotive, industrial, and military applications requiring high reliability, high precision voltage regulation. With its on-chip error amplifier, its excellent transient response, and its on-chip current monitoring, the device provides reliable, accurate, and efficient power management. The user can easily adjust the voltage levels and other parameters with an external, programmable control interface, making the device ideal for a wide range of analog and mixed-signal applications.
