The S-1711D4230-I6T1U is a linear regulator integrated circuit (IC) designed to maintain a fixed voltage across a power system. It is a member of the S-1711 family of voltage regulators, developed and manufactured by Semikron International. This device is a monolithic system in a single-package solution, offering improved power handling, operational safety and reduced cost for high-current applications.

Like most other linear regulators, S-1711D4230-I6T1U provides excellent protection against short-circuits and low-voltage variations. The device operates with a nominal voltage difference of 0.7 V between its input and output pins, with a maximum of 1.25 V. Its power output ranges from 1.6 A to 5.5 A, depending on the device operating temperature. The maximum temperature of operation is +85 oC.

This IC is extremely useful for applications where line-to-ground sensitivity or fast transient response is required, such as power supply design for various electronic systems or audio-video devices. It offers clear advantages with regard to reduced power consumption, low external components needed, and excellent noise suppression. Voltage drops can be safely handled through thermal shutdown protection and current limitation.

The S-1711D4230-I6T1U is usually utilized for electric power systems where a fixed voltage is necessary, in industrial and automotive applications, home and office electronics, telecom systems, and battery power converters. As a linear regulator, it is a device well known for its adequate supply of constant, fail-safe power extraction system.

The S-1711D4230-I6T1U device works on the simple principle of regulating voltage to maintain a steady supply at its output terminals. Whenever an input voltage is above the reference voltage, there will be a voltage potential difference between its input and output terminals. This potential difference is then amplified and regulated by the IC, forcing the output voltage to stay at the set level while the input voltage may vary. This can be visualized using a feedback loop, where the output voltage is constantly compared to a reference voltage and any deviation from the set level is corrected by adjusting the amplification of the IC, thus reducing or increasing the output voltage.

The use of a linear regulator eliminates the need for external components like inductors, capacitors or transformers, resulting in a simple, reliable, efficient and cost-effective solution for many electronic applications requiring linear regulation. The S-1711D4230-I6T1U is an excellent example of this type of device, providing excellent performance, high efficiency, and long-term reliability.
