S-1133B57-I8T1U

S-1133B57-I8T1U is an ultra-low dropout (ULDO) linear voltage regulator manufactured by True-Tech Electronics Inc. It is a three-terminal adjustable regulator that is capable of controlling voltage from an input voltage between 0.7V to 7V and provides output voltage between 0.7V to 6V within ± 1.5% accuracy. It features an enable pin with active high logic level and is available in a small 4-SOT-23 package.

The S-1133B57-I8T1U is designed for a variety of applications in the industrial, medical, consumer, and automotive Industries. It can be used, for example, in portable devices such as mobile phones, digital cameras, PDAs, DVD players, and so on; or it can be used in automotive applications such as car audio systems, HVAC systems, display backlighting, and so on. It is suitable for applications that require the added benefits of a ULDO linear regulator, such as improved noise rejection, improved efficiency, reduced power dissipation, and improved output filter performance. The device is also a great choice for applications where both high accuracy and fast line/load transient response are required.

The S-1133B57-I8T1U linear voltage regulator operates on the principle of negative feedback. The basic operating principle of a negative feedback loop is that if the output voltage is higher than the desired output voltage, then the internal circuitry of the voltage regulator reduces the current supplied to the output until the output voltage drops back to the desired value. Similarly, if the output voltage is lower than the desired output voltage, then the internal circuitry of the voltage regulator increases the current supplied to the output until the output voltage rises to the desired value. This negative feedback loop continues as long as the load stays constant, resulting in a stable output voltage that is maintained at the desired level.

The S-1133B57-I8T1U is an ideal solution for any application that requires an adjustable low input voltage linear voltage regulator. Its features include an enable pin with active high logic level and an ultra-low dropout that make it suitable for industrial, medical, consumer, and automotive applications. Its negative feedback operation ensures that the output voltage is maintained at a stable level in response to variations in the load.
