The S-1206B15-U3T1G is a three terminal fixed output voltage linear regulator specifically designed for cost sensitive applications. It often used in telecom, datacom, industrial and consumer electronic applications. So, this article will give an introduction to its application field and working principle.

Application Field

The S-1206B15-U3T1G is specifically designed to provide low cost voltage regulation solution for cost sensitive applications such as Telecom, Datacom, Industrial, and Consumer electronics. It has a wide input voltage range from 8V to 18V, which makes it suitable for different types of applications. Furthermore, It supports up to 6 watts of output power, meaning it can be used in a variety of power conditioning and distributed power architectures. In addition, this device has a typical efficiency of 84%, which further enhances its suitability for cost sensitive applications.

Working Principle

The S-1206B15-U3T1G output voltage is set by two external resistors, R1 and R2, which form a divider network between the VOUT and ground terminals. The output voltage is equal to the regulated output voltage (VREF) multiplied by the ratio of R1 and R2: VOUT = VREF*(R1/R2).

The S-1206B15-U3T1G uses a linear regulator, a trans-conductance amplifier, and a PNP transistor, to regulating the output voltage. The trans-conductance amplifier compares the output voltage to an internal reference voltage (VREF) and adjusts the output current accordingly. The PNP transistor is responsible for the pass element of the regulator and the output current is controlled by the trans-conductance amplifier.

The S-1206B15-U3T1G has internal overload protection and thermal shut down functions to ensure proper protection of the device. It also has an internal soft start function, which enables the device to start up with a more gradual increase in current and lower initial inrush current.

Conclusion

The S-1206B15-U3T1G is specifically designed for cost sensitive applications, like Telecom, Datacom, Industrial and Consumer electronics. It is a three terminal fixed output voltage linear regulator and it supports up to 6 watts of output power. The output voltage is set by two external resistors, which form a divider network between the VOUT and ground terminals. The S-1206B15-U3T1G also has internal overload protection and thermal shut down functions, as well as an internal soft start feature. The typical efficiency of this device is 84%, which makes it an excellent choice for cost sensitive applications.
