The S-812C45BMC-C4ZT2G is a linear voltage regulator that is part of a comprehensive range of PMICs (Power Management ICs) produced by Japan’s Renesas Electronics. This voltage regulator provides up to 45V maximum input voltage with a range of up to 5.0V nominal output voltage with a maximum application of 150 mA.

S-812C45BMC-C4ZT2G is designed for applications that require low total output noise and low residual noise under all operating conditions. Typical applications include automotive, industrial control, and consumer electronics. The device is built on a small 24-pin DIP package which means it can be used with a wide variety of circuits and systems.

The device is a low-dropout voltage regulator that provides better regulation under lower input voltages when compared to other linear voltage regulators. S-812C45BMC-C4ZT2G works by regulating the output voltage to within a 2% accuracy of the nominal output voltage. It includes a number of features to provide improved performance and reliability such as thermality protection and overvoltage protection.

Additionally, the device offers dropout voltage of 1.5V at full load, an internal temperature range of -40°C to +125°C and an operating temperature range of -20°C to +85°C. The device also has an input leakage current of 1µA maximum, an output voltage noise of 10µVrms and a load regulation of 0.01%. These features are designed to ensure reliable operation of the voltage regulator in a wide variety of applications.

S-812C45BMC-C4ZT2G’s working principle is based on a three-terminal linear regulator. The regulator has a reference input that determines the output voltage, an enable input which controls the output and a feedback loop. When the enable input is high and the feedback loop is closed, any variation in the input voltage is compensated by the difference between the reference input and the output voltage. This ensures that the output voltage remains at a constant level, regardless of the input voltage variations.

In summary, the S-812C45BMC-C4ZT2G is a low-dropout, three-terminal, linear voltage regulator for use in a variety of applications. It offers low total output noise and low residual noise, and has a wide operating temperature range to ensure reliable operation in challenging environments. The device is designed for use in automotive, industrial control and consumer electronics, providing improved regulation and performance for reliable operation. The device is also easy to integrate in a circuit due to its small 24-pin DIP package.
