The S-1135D18-M5T1U is a versatile linear voltage regulator that provides a steady voltage up to 18V from a supply voltage between 4.5 and 18V. It has a dropout voltage of 1.35V, making it suitable for a wide range of applications and power requirements. The regulator has a low quiescent current of 1.5mA and a temperature operating range of -40°C to +85°C.

Application Field

The S-1135D18-M5T1U linear voltage regulator is an excellent choice for low power application requirements. The versatility of this regulator makes it ideal for applications such as industrial/automotive control, power supplies for small electronic devices and medical equipment.

The regulator is also suitable for applications such as 3D printers, computer peripherals, embedded systems, test and measurement equipment, automotive systems and robotics servos, to name a few. This is due to its ability to provide low, reliable and constant output voltage.

Working Principle

The working principle of the S-1135D18-M5T1U linear voltage regulator is largely based on the concept of a Feedback System. This system works by constantly measuring the output voltage of the regulator and comparing it to the desired setpoint. Any deviation from the setpoint is corrected by the system using proprietary algorithms.

The S-1135D18-M5T1U regulator employs a sophisticated comparator system to measure the output voltage. The output of the regulator is then controlled by varying the voltage across the device’s internal field-effect transistor, or FET, based on the detected deviation from the setpoint. The regulator also includes protection from over current, overvoltage, and overtemperature conditions.

The S-1135D18-M5T1U linear voltage regulator is an excellent choice for low power application requirements. This versatile device is capable of providing a reliable, constant output voltage up to 18V from a supply voltage between 4.5 and 18V. Its low quiescent current and temperature range make it suitable for a wide range of applications and power requirements. The working principle is also based on the concept of feedback systems, making it further reliable.
