Working Principle

The AS1359-BTTT-27 is a linear voltage regulator that regulates the output of a DC power supply by providing a stable, fixed output voltage. It works by comparing the output voltage to a reference voltage and then adjusting the output voltage accordingly. The regulator will adjust the output voltage either up or down depending on the input voltage and the load being driven. It does this by passing a small current from the input terminal to the output terminal, which leads to a voltage across the load. This current is controlled by an internal error amplifier, which ensures that the output voltage remains constant even with changes in load current.

The AS1359-BTTT-27 has a wide input voltage range that allows it to be used to regulate the output of various sources including nominal voltages, batteries, and high-voltage supplies. It also offers current-foldback, which reduces the amount of power delivered as the load increases. This allows it to be used in applications with high loads and still maintain reliable voltage regulation. Additionally, this device has an adjustable voltage range, which provides flexibility in applications that require different output voltages.

Conclusion

The AS1359-BTTT-27 is a small surface-mount linear voltage regulator that can provide consistent, reliable voltage regulation in a wide variety of applications. With its wide input voltage range, adjustable output voltage range, and current foldback, it is an ideal solution for many power solutions. The device is also fully protected against over-current and over-temperature, and has a wide range of safety and EMC certifications. In summary, the AS1359-BTTT-27 is an excellent choice for applications requiring reliable voltage regulation and safety-critical operations.
