Application Field

S-1137A12-U5T1U is a general purpose linear voltage regulator used in a wide range of applications. It is mainly applied in portable device such as smartphones, tablets, etc. It is able to serve as a low-noise supply for audio and video devices, as well as other energy-efficient applications. It is also suitable for many other applications such as automotive, industrial and consumer electronics.

Working Principle

S-1137A12-U5T1U is a linear voltage regulator with a wide range of input voltage, which allows sufficient voltage to operate a device after the voltage has been heavily reduced. It utilizes a feedback loop that maintains the desired output voltage across its output terminal. This can be done by comparing the output voltage to a reference voltage – usually a bandgap reference voltage – and using this comparison to adjust the current through an adjustable resistor, thus increasing or decreasing the output voltage. In this way, the output voltage is stabilized.

S-1137A12-U5T1U has a very low dropout voltage, which means that the output voltage is very close to the input voltage. As the input voltage increases, the output voltage also rises slightly. This makes S-1137A12-U5T1U an ideal choice for applications that require an accurate, low-noise and low-dropout voltage regulation.

S-1137A12-U5T1U is a highly reliable voltage regulator equipped with a range of protection features like built-in overcurrent protection that prevents the device from overloading, making it suitable for a variety of applications.
