S-812C46BPI-C5ATFU

The Linear Voltage Regulator, or LVR, is a power management integrated circuit (PMIC) designed to provide reliable, consistent voltage outputs in order to support a host of electronic systems. As its name suggests, the LVR is most often used to regulate voltage outputs from a primary power source to one or more secondary circuits. In addition to its role in watt manage-ment, the LVR is often used to program logic levels and act as a signal amplifier for various communications systems. Popular for its ability to steady output voltage and smooth fluctuations in input current, the Linear Voltage Regulator is a vital component in power management systems.The S-812C46BPI-C5ATFU is a LVR designed by Japan-based manufacturer Rohm Semiconductor. As an integrated power management device, the S-812C46BPI-C5ATFU offers a wide range of power input options ranging from 5.0V to 20.0V, allowing it to be adapted to virtually any power input source. The device’s adjustable voltage output range is 5.0V to 15.0V and its maximum output current is 200 milliamps (mA). In addition to voltage regulation, the S-812C46BPI-C5ATFU features short circuit protection, over-voltage protection, over-temperature protection, and current limiting.The S-812C46BPI-C5ATFU is typically used in devices with complex power supply systems, such as smartphones, tablets, digital cameras and portable devices. Highly integrated and customizable to various applications, the S-812C46BPI-C5ATFU is well-suited for analog and mixed-signal environments. The part is available in a tiny surface-mount package, allowing it to be easily integrated onto small or densely populated printed circuit boards (PCBs).At the heart of the S-812C46BPI-C5ATFU is a Linear Voltage Regulator circuit, consisting of two transistors, two diodes, two resistors and two capacitors. This circuit is designed to regulate voltage when the input voltage exceeds the output voltage and to provide protection against short-circuiting and over-voltage. Working in combination with pulse-width modulation (PWM) control, the Linear Voltage Regulator stabilizes voltage input and output levels.The Linear Voltage Regulator compensates for fluctuations in power supply levels by converting the electricity from the input source into a form that matches the output source. This is achieved by adjusting the amount of current flowing through the transistors, and thus the amount of voltage produced. This process is known as “switching” and is why the S-812C46BPI-C5ATFU requires a certain amount of switching time to carry out voltage conversion. In the most practical applications, switching time is lower than 20 microseconds, allowing the device to quickly adjust to changing input sources without major disruption.To provide additional stability, the S-812C46BPI-C5ATFU is typically fitted with two capacitors at the input and output terminals. These capacitors act as energy storage reservoirs and are connected in parallel to the circuit’s input and output terminals. The capacitor at the input stores energy from the source in order to meet sudden changes in output voltage. At the same time, the capacitor at the output stores energy to meet sudden drops in input voltage. Together, these capacitors help the S-812C46BPI-C5ATFU maintain a relatively steady input and output voltage.In a nutshell, the possibilities of the S-812C46BPI-C5ATFU Linear Voltage Regulator are endless. By providing a reliable voltage output, it serves as a vital component in many electronic systems. Its wide input and output potential, ability to deliver consistent voltage levels and comprehensive built-in protections make it an ideal option for power management applications.
