S-1721E1826-M6T1U

Linear voltage regulators convert an input voltage to a steady output voltage with minimal variation as the input voltage changes. They are commonly used to store and manage power from a variety of sources and to regulate the output from the power supply to the processor. The S-1721E1826-M6T1U is a three-terminal adjustable linear voltage regulator from Murata, intended for a wide range of applications requiring adjustable positive voltage and current regulation.

Application Field

The S-1721E1826-M6T1U is designed to regulate and supply power in a wide range of industries, especially those in which small to medium power requirements are necessary. It is especially useful in circuit designs which need an adjustable voltage source, such as low-voltage power supplies, personal electronics, measuring instruments, and data logging systems.

The device can output a current of up to 150mA, making it well-suited for powering traditional analog circuits and low-power digital systems. The output voltage range is adjustable between 1.2 and 19.2 volts, which provides great flexibility when it comes to powering different components. The device also has a wide temperature range, which makes it an excellent choice for applications where the ambient temperature is frequently changing.

Working Principle

The S-1721E1826-M6T1U utilizes an internally trimmable voltage reference to set the output voltage. The voltage is monitored by a feedback circuit, and any output voltage variation is immediately compensated by increasing or decreasing the power supply current. This allows the regulator to maintain a steady output voltage even if the input voltage changes.

The device also uses a novel thermal protection circuit to protect itself from damage due to over current or over temperature conditions. This circuit rapidly reduces the output current to prevent excessive heat build-up, and will then reset the current limit if safe operating conditions are restored.

In addition, the device has a low dropout voltage, which allows it to achieve high efficiency over a wide range of current levels. With an input voltage range of up to 30 volts, the S-1721E1826-M6T1U can be used in demanding applications with higher voltages.

The S-1721E1826-M6T1U offers simple installation and is compliant with the RoHS and Reach directives. The device is also constructed using halogen-free package material with minimal environmental impact.

Conclusion

The S-1721E1826-M6T1U is a three terminal adjustable linear voltage regulator from Murata. It can output a steady current of up to 150mA, and its adjustable output voltage range of 1.2 to 19.2 volts provides great flexibility for a variety of applications. Additionally, the device’s low dropout voltage and thermal protection circuit help ensure that it remains stable and efficient under a wide range of operating conditions.
