This device is suitable for providing a stable output voltage for a wide range of applications and is able to deliver up to 150mA of current.

Application Field

The S-812C31BMC-C4LT2G is a versatile and feature-rich linear voltage regulator that is suitable for a wide range of applications. It can be used in a range of low-power applications, such as portable electronics, LCD backlight controllers, LED drivers, automotive, power management ICs (PMICs) and AC/DC adapters.The regulator has an adjustable output voltage range of 1.2V to 5.5V and is capable of providing a fast transient response and a low dropout voltage. The wide input voltage range and low quiescent current make it ideal for battery powered applications. Furthermore, the S-812C31BMC-C4LT2G is designed to comply with the AEC-Q100 automotive product qualification requirement.

Working Principle

Linear voltage regulators, such as the S-812C31BMC-C4LT2G, work on the principle of controlling an output voltage by controlling the amount of current that passes through a transistor. The current is controlled by adjusting the voltage across the transistor using feedback from the output voltage.When the input voltage supplies more current than the load requires, the excess current is diverted to a current-limiting circuit. When the input voltage is too high, the linear voltage regulator limits the amount of voltage that passes through the output.The S-812C31BMC-C4LT2G is a low dropout (LDO) voltage regulator, which means it has a very low voltage dropout at the output. This is because it is designed with a very small internal resistance, allowing more current to pass through the regulator with less voltage drop.
