Introduction

The S-812C52AMC-C3GT2G is a voltage regulator produced by Sanken Electric Co., Ltd. The S-812C52AMC-C3GT2G is a linear voltage regulator, meaning that it regulates the power supply to within a certain, constant voltage by using a device to maintain this voltage as the load increases and decreases. The linear voltage regulators provide a steady output, but have limitations due to their slow response time, components required, and the slow change in voltage with respect to time.

Application Field

The S-812C52AMC-C3GT2G is primarily used in automotive and transport applications. This regulator is specifically designed for applications such as active safety systems, advanced driver assistance systems (ADAS), vehicle navigation, infotainment systems and in-vehicle electronics. This voltage regulator provides a precise, reliable operating voltage to help ensure automotive components run safely and efficiently.

Working Principle

The S-812C52AMC-C3GT2G works much like any other linear voltage regulator. Electricity passes through a circuit and the regulator measures the incoming voltage and then adjusts the output to a preset voltage. The voltage regulator consists of two essential parts, a voltage reference and an error amplifier. The reference section produces a stable, low-impedance voltage signal and this is used as the setpoint by the error amplifier. This signal is compared against the output voltage and the error amplifier is used to adjust the circuit so that the output signal matches the reference.For increased precision, the S-812C52AMC-C3GT2G also features a programmable overcurrent protection and an enable pin. The overcurrent protection monitors the current flowing through the regulator and will shut down the output if the current exceeds the programmed level. This allows for safe operation of the regulator and helps to protect against power surges and short circuits.

Conclusion

The S-812C52AMC-C3GT2G is an ideal solution for automotive and transport applications. Its linear voltage regulation capabilities provide reliable output voltage with programmable levels of protection. With tight tolerances, low quiescent currents and a wide operating temperature range the S-812C52AMC-C3GT2G is suitable for a wide range of automotive and transport applications.
