The S-1135B19-U5T1G is a monolithic integrated circuit designed for use as an adjustable output, low-dropout three-terminal positive regulator. This device has built-in current limit, thermal shutdown and safe-area protection, making it exceptionally easy to use and highly reliable.

The S-1135B19-U5T1G falls under the category of PMIC - Voltage Regulators - Linear, and is primarily utilized as a guide for the development of various electrical applications. Some of the most common application fields include power supplies, battery chargers and current/voltage sensing regulators.

The application field and working principle of the S-1135B19-U5T1G is relatively straightforward. It is a voltage regulator, meaning its main function is to maintain a specific voltage level at its output regardless of the input voltage or load variations. There are three terminals on the regulator – an input terminal, an output terminal, and an Adjust (ADJ) terminal.

The input terminal is connected to a higher voltage source, whereas the output terminal is connected to the load which needs to be powered. The Adjust terminal allows for precise adjustment of the output voltage to the required supply level. When the adjustment terminal is used, the voltage at the output terminal can be varied between a minimum of 1.25V up to a maximum of 37V, depending on the model.

At its core, the S-1135B19-U5T1G operates on the simple principle of voltage regulation. As the input voltage increases, the regulator will automatically adjust its output voltage as required to maintain the preset output voltage. This keeps the downstream components from risking an overvoltage condition.

The S-1135B19-U5T1G provides excellent performance, with a very low dropout voltage and very good load and line regulation. It has low output noise and temperature coefficient, and can provide up to 1.5A of load current. The device also has a built-in current limit and thermal shutdown circuitry, which helps protect the device and the downstream components from damage in case of an overload.

The S-1135B19-U5T1G is an efficient, reliable and cost-effective device suitable for a wide range of applications. It can be used to generate regulated DC voltages for powering a variety of devices, such as microcontrollers, FPGA, DSPs and other components which require an exact voltage for their operation. It can also be used as a buffer for audio and video circuitry, power-supply sequencing, and to safely monitor and regulate power consumption.
