S-1112B29MC-L6OTFU Application field and Working Principle

A linear voltage regulator, like the S-1112B29MC-L6OTFU, is an electrical circuit used to provide a stable output voltage from an input voltage source that can vary significantly. The output voltage is regulated in such a way that the difference between the output and the input stays constant, regardless of the load conditions. Voltage regulators are often used in electrical devices to ensure that the power delivered to electronic circuits remains constant, even under varying line voltage, load current, and temperature conditions.

Application field

Linear voltage regulators are commonly used in many different types of electronic devices and equipment, such as computers, battery chargers, LED drivers, industrial equipment, communication devices and power supplies. These regulators are widely used due to their flexibility, low cost and ease of implementation. They are capable of providing a very steady and stable output voltage, even under varying input voltage and load conditions.

The S-1112B29MC-L6OTFU is one of Seiko\'s renowned low dropout (LDO) linear regulators. It delivers excellent regulation performance and is capable of providing highly precise and precise output voltage settings, up to ±1%. With its high efficiencies, low voltage drops and low quiescent current of 120μA, it is an ideal choice for numerous power supply applications.

Working Principle

The working principle of a linear voltage regulator (LDO) is relatively simple. The regulator uses a series of resistors, capacitors and transistors to create a negative feedback loop to control and adjust the output voltage according to the difference between the actual output voltage and the intended voltage. When the output voltage drops below its specified level, the regulator\'s output circuit will turn the N-channel transistor on, drawing more current from the supply, which increases the output voltage. This continues until the output voltage is returned to its original level.

The switching of the N-channel transistor is controlled by a built-in internal voltage reference that is preset by the user. This internal voltage reference can be adjusted to ensure the output voltage remains at its desired level. The reference voltage is typically adjusted using a potentiometer or a trimmer.

The linear voltage regulator (LDO) can also provide a variety of features, such as overcurrent protection, thermal shutdown and current limiting, which ensure a safe and reliable operation. Depending on the specific model, the output voltage can range from 1.2V to 24V, with output currents of up to 1.0A.

Conclusion

The S-1112B29MC-L6OTFU is an LDO linear voltage regulator that offers excellent stability and precise output voltage settings, making it an ideal choice for a wide range of applications. Its built-in features, such as thermal shutdown and overcurrent protection, ensure a safe and reliable operation, even under varying input voltage and load conditions. Its low-voltage drop and quiescent current of 120μA also make it an economical choice for many power supply applications.
