PMIC (Power Management Integrated Circuit) is an integrated circuit that operates to monitor and control the power of an electronic system. It consists of various sections such as voltage regulators, battery charging and management, power supply sequencing, power dissipation, and over voltage and over temperature protection, to name a few. PMICs play an important role in managing the power needs of the system. Linear voltage regulators are an important class of PMICs and often found on printed circuit boards as a single integrated unit. The S-812C36BMC-C4QT2G is one such PMIC linear voltage regulator that is used in various types of applications.

The S-812C36BMC-C4QT2G is a single-channel, high-performance, low-dropout (LDO), linear voltage regulator with an operating temperature range of -40°C to + 125°C. It offers a range of adjustable voltage output from 0.89V to 5V, with a maximum output current of 1.2A. The regulator has an internal power dissipation of 7.5mW @ 1.2A and a quiescent current of 550μA. The S-812C36BMC-C4QT2G has a typical line regulation of 0.015%, a typical load regulation of 0.05%, and a transient response of 10μs (at 50mV deviation). In addition, the S-812C36BMC-C4QT2G has high ESD protection (up to 4kV). It is also very efficient, with an efficiency rating of up to 90%.

The S-812C36BMC-C4QT2G is an ideal choice for use in a variety of applications, such as computers and mobile phones, digital cameras and webcams, wireless communication systems, digital TV and set-top boxes, portable audio/video players, HDDs and SSDs, gaming consoles, and industrial and medical equipment. Its wide input voltage range of 2V to 7V makes it suitable for various power sources, such as a 12V power supply, a 5V USB power source, a lithium battery, and a fuel cell. Its operating temperature range makes it suitable for use in extreme temperature environments.

The S-812C36BMC-C4QT2G is based on a linear control topology. It offers a stable voltage output with very low noise, and has a very high PSRR for local noise reduction. It works on the same principle as a resistor-divider, where an input voltage is applied across two resistors, one of which is variable. The output voltage is determined by the ratio of the two resistors. The variable resistor is connected to an error amplifier, which compares the output voltage with the desired voltage, and adjusts the variable resistor accordingly. The output voltage is thus regulated according to the error amplifier’s feedback, with no external components required.

The S-812C36BMC-C4QT2G also has several features to protect the circuit from over-current, over-voltage, and thermal overload. It has an output voltage trip level of 5.5V, and a thermal shutdown level of 150°C. The output is protected against short circuit conditions, with automatic recovery after the overload is removed. The S-812C36BMC-C4QT2G also offers internal current limiting, which limits the output current to 1.2A.

In conclusion, the S-812C36BMC-C4QT2G is an ideal choice for applications that require a low-dropout and high-performance linear voltage regulator. It offers a wide range of adjustable output voltage and a wide temperature range, making it suitable for a variety of applications. It also has a number of features, including short-circuit protection and thermal overload protection. The S-812C36BMC-C4QT2G is a robust and reliable solution for power management and voltage regulation.
