S-817A20APF-CUJTFU is one of the most widely used voltage regulators today, and is a linear type voltage regulator. It belongs to the Power Management Integrated Circuit (PMIC) family of parts and plays an important role in managing and stabilizing the flow of power within devices. It is frequently used in a wide range of industrial, consumer, and energy applications.

The S-817A20APF-CUJTFU is a high performance, cost-effective, and efficient regulator. It provides up to 20A continuous output current and up to 30A peak output current with low quiescent current of 0.2mA. It offers a wide input voltage range of 4.5V to 20V, making it suitable for a wide range of applications including automotive, consumer, industrial, and portable applications. The output voltage range is adjustable between 0.5V and 4.5V and offers very high accuracy with a maximum tolerance of ± 5%.

The S-817A20APF-CUJTFU is also capable of delivering very high power efficiency (up to 94%) and fast load transient response due to its fast loop compensation circuitry. It also provides a wide temperature range from -40°C to 125°C. Additionally, it offers device-level protection features such as overcurrent protection, overvoltage protection, and shutdown temperature protection. This helps to protect the device from accidental damage or misuse in applications where high power levels may lead to abnormal conditions.

The S-817A20APF-CUJTFU functions as a voltage regulator and works by using an error amplifier and a feedback resistor to feed back the output voltage and compare it to the reference voltage. The output voltage is then adjusted by the error amplifier, depending on the difference between the set and measured voltage. This allows the voltage regulator to maintain a steady output voltage despite fluctuations in the load or input voltage.
