Introduction
The S-1142B85I-E6T1U is a linear voltage regulator manufactured by STMicroelectronics and belongs to the Power Management Integrated Circuit (PMIC) family of products. This voltage regulator is a low dropout (LDO) type and is typically used for supplying low voltage regulated outputs to circuits and for dynamic voltage scaling applications. It can deliver up to 100mA of continuous output current and its output voltage is adjustable from 0.9V to 11.4V. The device is capable of operating from a wide input voltage range of 2.5V to 40V.

Application Field and Working Principle
The S-1142B85I-E6T1U is a versatile power management device that can be used in a variety of applications, including automotive, industrial, and consumer applications. It can be used in power-global applications to provide regulated supply voltages to microcontrollers, digital signal processors, ASSPs and FPGA circuits. It is also used in A/D or D/A converters and digital audio systems. In automobile applications, this device can be used to regulate the voltage of the 12-volt automotive battery.The S-1142B85I-E6T1U voltage regulator operates using the principle of linear voltage regulation. A typical linear regulator will use an internal transistor to drop the difference between the input and output voltage in voltage series configuration. When the input voltage is greater than the output voltage, current from the input flows through the internal transistor, which acts as a linear resistance element. The current through the transistor produces a voltage drop across the transistor, and the voltage drops across the transistor add up to the output voltage. This reduces the output voltage to the desired level. When there is a decrease in the input voltage, the transistor reduces the amount of current passing through it and this helps to maintain the output voltage constant.

Features
The S-1142B85I-E6T1U features high current output capability of up to 100mA and a wide operating input voltage range of 2.5V to 40V. It has low dropout voltage of 0.9V and can be operated over a temperature range of –40°C to +125°C. It features current limiting, over-current protection, thermal protection and reverse polarity protection. The device also features quiescent and shutdown current specifications to provide a power efficient solution. The device is available in an industry-standard SOT-223 package, allowing for easy implementation into existing systems.

Conclusion
The S-1142B85I-E6T1U is a low dropout (LDO) voltage regulator designed to provide a wide operating input voltage of up to 40V and a low dropout voltage of 0.9V. It is designed for use in a variety of applications, such as automotive, industrial, and consumer applications, and is capable of delivering up to 100mA of continuous output current. The device is available in an industry-standard SOT-223 package, allowing for easy integration into existing systems.
