• Intermittent control systems
• Temperature control systems
• Servo systems
• Conversions of other attributes/variables
• Wireless communication systems

Features & Advantages

The S-1206B41-U3T1G feature mix includes:

• Output voltages of +/-5V
• Low power drain
• Good output accuracy
• Noise protection
• Extremely small form factor
• Seiko-Epson quality and reliability

Working Principle

The S-1206B41-U3T1G uses a linear voltage regulator to achieve +/-5V output voltages. In this kind of power supply system, power is derived from an input voltage source and regulated to a lower voltage which will be used to power the circuit. A linear voltage regulator architecture is more straightforward than a switch-mode regulator, with simpler internal operating steps. The main components of this linear voltage regulator set are SCMA11N45 and SC2766, while S-1206B41-U3T1G itself includes all necessary components for regulating the output voltage.

The SCMA11N45 works as a voltage control terminal voltage stabilizer. It takes in a voltage from an medium voltage terminal to feed power to the circuit. This terminal voltage will be supplied to the SC2766, which is a positive voltage stabilizer equivalent to two single-ended voltage stabilizing elements (two SC2766s in one package). This is where the +output, -output, and ground of the S-1206B41-U3T1G are generated.

Conclusion

The S-1206B41-U3T1G has a wide range of applications in the industrial sector, due to its high precision, low power consumption, and small size. It uses a linear voltage regulator technology which is proven to be reliable and robust. With these characteristics, the S-1206B41-U3T1G is a sound choice for any voltage regulation needs.
