The Application Field and Working Principle of S-1135C28-U5T1U

The S-1135C28-U5T1U is a low-dropout (LDO) linear voltage regulator that incorporates the latest advancements in semiconductors to ensure optimum performance and reliability in a wide range of applications. It is designed to provide a highly regulated and stable output voltage while relieving strain from the power supply. This device is suitable for a variety of electronic and electrical applications, such as computers and peripheral equipment, together with any system requiring an independent and stable power source.The S-1135C28-U5T1U is rated for an input voltage of 6 V and an output voltage of 5.0 V with a maximum line regulation tolerance of ±0.3%. It is capable of dissipating a maximum continuous current of 1 A. Furthermore, the has an on-off control pin which makes it suitable for applications that require on-off control, such as battery backup systems. The S-1135C28-U5T1U also features a thermal shutdown function which will turn off the output if the device gets too hot and an over-temperature protection which will restart the output if the temperature has not exceeded its maximum operating temperature.The working principle of the S-1135C28-U5T1U is relatively simple. It consists of an input transistor, a driver, an output transistor and an error amplifier. When the input voltage is applied to the input transistor, the driver circuit provides an optimum base current to the output transistor, to adjust the output voltage to the predetermined voltage levels. The error amplifier compares the output voltage with a precision reference voltage, that is, the output voltage is maintained within a fixed range by controlling the current to the output transistor by means of the error amplifier.In addition to providing a highly regulated output voltage, the S-1135C28-U5T1U also provides excellent current-limiting protection. This means that it will shut off the output circuit immediately when it detects an overload condition. This feature makes it suitable for use in applications that are subject to short-term, transient over-current conditions, such as those caused by short circuits.In summary, the S-1135C28-U5T1U is a versatile and high-reliability linear voltage regulator capable of supplying a regulated and stable output voltage. It is designed to provide efficient power management and robust protection against overloads and temperature fluctuations. Its features make it well suited for a range of applications, including computers and peripheral equipment, automotive systems, and portable and industrial electronics.
