Working Principle

The S-875271CUP-AHAT2U is a linear voltage regulator that works by regulating an adjustable input voltage. The input voltage is adjustable through an external voltage divider network, or by taking its reference voltage from an external source. The output voltage of the regulator is then set to the desired value using the external feedback pins. During operation, the linear regulator maintains a constant output voltage regardless of changes in input voltage or load. The internal circuitry of the regulator contains a series pass element like a transistor or FET, a bias/sense element and overload/short-circuit protection circuitry. The bias/sense element is used to compare the output voltage with the reference voltage, and adjusts the series pass element to maintain the reference voltage. The overload/short-circuit protection circuit is used to ensure that the output voltage does not exceed the absolute maximum level.

Conclusion

The S-875271CUP-AHAT2U is an ideal linear voltage regulator for a variety of applications, including power supplies for mobile devices, MCU/MPU core voltage supplies, power supplies for general-purpose electronics and telecommunications equipment. It features a wide range of input and output voltages, fast transient response time, low dropout voltage, exceptional short circuit and overload protection, low leakage current, reverse leakage current and very low noise. It also offers low power consumption, improving efficiency and prolonging battery life. The S-875271CUP-AHAT2U is therefore the ideal choice when a reliable, low-power voltage regulator is required.
