S-1721A2826-I6T1U

The S-1721A2826-I6T1U is a linear voltage regulator, which falls under the Product Manageability and Intelligence (PMIC) category. A linear voltage regulator, when powered, reduces and maintains the output voltage at a constant level regardless if the voltage of the input power source fluctuates. This particular device is classified as an adjustable positive voltage regulator, meaning it is able to deliver output voltage values greater than its input voltage. It features an adjustable output voltage range of 1.2V to 20V with a current capability of up to 2.5A, making it suitable for a wide range of applications.

Applications

The S-1721A2826-I6T1U is well suited for use in applications such as powering microprocessors, FPGAs, ASICs and DSPs. It can also be used in portable electronic devices such as mobile phones, medical devices, communications and consumer electronics. The adjustable output voltage makes it suitable for applications where precision voltage levels are required.

Working Principle

The S-1721A2826-I6T1U features an error-amplification circuit that ensures output voltage accuracy. This is achieved by comparing the voltage of the regulated output against a selectable internal reference voltage. The difference between the two voltages is amplified and used to control a pass element which regulates the output. When the output voltage deviates from the set level, the error circuit detects the difference and corrects it by driving the pass element until the output equals the reference voltage. This process is repeated until the output voltage is accurately maintained at the value the user has set.

In addition, the S-1721A2826-I6T1U features current limit protection and thermal overload protection. The current limit protection prevents an overload of the power supply, while the thermal overload protection helps to keep the chip from overheating in extreme conditions.

Conclusion

The S-1721A2826-I6T1U is a linear voltage regulator under the PMIC category. It can be used in a wide range of applications, such as powering microprocessors, FPGAs, ASICs and DSPs. The adjustable output voltage makes it suitable for applications where precision voltage levels are required. The device features an error-amplification circuit, current limit protection and thermal overload protection, which ensures output voltage accuracy, as well as preventing an overload of the power supply and overheating. With its adjustable output voltage range and current capability of up to 2.5A, the S-1721A2826-I6T1U is well suited for a variety of applications.
