S-812C28BPI-C4ITFG Application Field and Working Principle

S-812C28BPI-C4ITFG is an integrated, low dropout linear voltage regulator (LDO) released by Shindengen, a leading provider of power semiconductor solutions and services. A voltage regulator is a device or circuit used to maintain a constant output voltage, regardless of changes in input voltage, current, and load condition. It can also be used to ensure the stability of the output voltage.

The S-812C28BPI-C4ITFG is designed specifically for applications requiring an input voltage range of 4.5 to 28 V and an adjustable output voltage range of 0.83 to 10V. This device is a high performance, low dropout linear regulator, with a control circuit, reference voltage circuit and MOSFET package built into one chip, equipped with current and thermal protection, to achieve a highly accurate output voltage. It is ideal for a wide range of applications including personal computers, portable equipment, automotive electronics and industrial control.

Working Principle

The S-812C28BPI-C4ITFG works on the principle of linear regulation. Linear regulation is achieved by setting the output voltage of the regulator by adjusting the reference voltage to match the required output voltage. The reference voltage is then compared with the incoming voltage through an error amplifier. The amplified difference is then used to control the conduction period of the MOSFET, thus regulating the output voltage of the device.

In the S-812C28BPI-C4ITFG, the error amplifier has both high gain and low output and can track the voltage at a speed faster than the conventional linear regulator. This allows the output voltage to be accurately regulated even with a large change in the input voltage or load current. The quiescent current is also extremely low, allowing for a longer battery life for applications where power conservation is important.

Applications

The S-812C28BPI-C4ITFG is an ideal choice for applications that require a high accuracy, low dropout linear regulator. It is particularly suitable for systems where power conservation is important. Due to its high performance and wide input voltage range, the device is suitable for a variety of applications including:

• Personal Computers
