AS431ARTR-E1 is a precision Voltage Reference which is typically used in applications such as battery-operated systems, portable systems, automotive, consumer, industrial and medical applications. It is constructed of Polysilicon film, monolithic integrated circuit (PMIC) technology and is offered in a tiny SOT-23 package. AS431ARTR-E1 is capable of providing a regulated two-terminal voltage of up to 6V, which is useful in a variety of applications.

The AS431ARTR-E1’s key features include low output noise and low drift over temperature. The output noise is approximately 10μV peak-to-peak, and the temperature drift is typically 0.5mV/K. In addition, it features an ultra-low quiescent current of only 150μA, so it is suitable for use in battery-powered applications.

The AS431ARTR-E1 operates on ranges from 2.5V to 6V. In addition to its voltage reference output, it also provides a separate reference terminal equal to its output. This is useful for applications such as setting the current through LED or LED arrays. The output voltage accuracy is only 0.15%, and there are no excess voltage drops associated with the device.

The AS431ARTR-E1 features a wide operating temperature range from -55°C to +125°C, so it is suitable for use in applications ranging from the coldest climates to the hottest. It also features an open-drain current RAM-ARTM at the timer output which can be used for timer applications, as well as a logic power on-chip control which can be used for microcontroller monitoring. The level of logic control is programmable, allowing users to easily switch between different modes.

The AS431ARTR-E1’s working principle is relatively simple. It utilizes an internal bandgap voltage reference which is maintained by an on-chip adjustable regulator, which sets the exact output voltage of the device. This output voltage is then injected into a precision resistor network, which allows the output voltage to remain constant regardless of temperature and voltage fluctuations.

The AS431ARTR-E1 is an extremely reliable device, being able to withstand ESD events of up to 8kV, as well as water immersion up to 1m for 1 hour. It is also RoHS compliant, and features a variety of protection features such as overvoltage and current limit protections. In addition, it features a power-down function which can be enabled by a low logic level on the pin for the Cut-Off Control. This feature allows the device to remain in standby mode, consuming only 3μA.

In summary, the AS431ARTR-E1 is an excellent choice for precision voltage reference applications. It offers low output noise and very low drift over temperature, and it operates on a wide voltage range with a high accuracy output voltage. In addition, it is extremely reliable, featuring an extended operating temperature range, an open-drain current RAM-ARTM at the timer output, and a logic power on-chip control. Finally, it is RoHS compliant and includes a power-down function, making it the perfect choice for a variety of applications.
