Introduction of S-1165B34MC-N6TTFU

The S-1165B34MC-N6TTFU is a Linear Voltage Regulator (LVR) integrated circuit (IC) from SEC (Seiko Electronic Components Inc.). It is a low-dropout regulator that provides an output of 3.3V, with a maximum current of 1.4A. In addition, it also has an extremely low operating temperature range of -40 °C to 125 °C. This makes it an ideal voltage regulator for a variety of applications, including microcontrollers, automotive, industrial, and medical equipment.

Application Fields of S-1165B34MC-N6TTFU

The S-1165B34MC-N6TTFU is used in a wide variety of applications. Some of the most common applications include:

Power Supplies and Chargers

The LVR is commonly used in power supply and battery charger circuits. It can convert an input voltage range of 4.5V to 24V to a regulated 3.3V output, making it an ideal choice for DC/DC converters, AC/DC adapters, and USB chargers.

Automotive Electronics

The LVR is also very popular in automotive electronics. It is used in automotive fuel injection systems, airbag systems, engine control units, climate control systems, infotainment systems, and power supply circuits, among other applications. Its low operating temperature range makes it suitable for use in harsh, hot environments, such as in cars or trailers.

Industrial Equipment and Medical Devices

The S-1165B34MC-N6TTFU is also used in industrial equipment, such as industrial controllers, motor controllers, and programmable logic controllers (PLCs). Its low operating temperature range makes it suitable for reliable operation in industrial environments, as well as medical devices.

Working Principle of S-1165B34MC-N6TTFU

The S-1165B34MC-N6TTFU is an LVR IC that regulates the input voltage to a specified output voltage. It is capable of converting an input voltage from 4.5V to 24V to a regulated 3.3V output voltage. This is achieved by using an internal comparator, which compares the input voltage with the output voltage. If the input voltage is higher than the output voltage, the comparator reduces the output voltage to maintain the desired level. The LVR IC also includes several protection features. It is equipped with an over-current protection circuit that shuts down the output voltage when the current exceeds a specified threshold. In addition, it also includes short-circuit protection, thermal protection, and a reverse voltage protection circuit. This ensures reliable operation and protects the IC from damage in the event of a short circuit or reverse voltage.

Conclusion

The S-1165B34MC-N6TTFU is a linear voltage regulator integrated circuit from SEC. It is a low-dropout regulator that provides an output of 3.3V, with a maximum current of 1.4A and an operating temperature range of -40 °C to 125 °C. It is used in a wide variety of applications, including power supplies and chargers, automotive electronics, industrial equipment, and medical devices. It works by using an internal comparator to compare the input voltage to the output voltage, and reduce the output voltage if the input voltage is higher. In addition, it includes several protection features, such as over-current, short-circuit, thermal, and reverse voltage protection circuits.
