A voltage reference is a device that produces a consistent, fixed output voltage regardless of changes in temperature, current or load. The ZXRE250BW5-7 is a precision 5.7V voltage reference designed to provide a very accurate output voltage and to require no external adjustments. The device has a low temperature coefficient, good accuracy, fast turn-on time and low noise, making it suitable for a variety of applications.

The ZXRE250BW5-7 is a 3-pin SOT-23 voltage reference that provides a high output voltage accuracy of 1.0%, good line regulation, low temperature drift and good load regulation. The device is particularly suited to low-voltage microprocessor-based systems and valve operated systems. The device can also be used as a voltage buffer and a supply for low power microcontrollers such as transistors and integrated circuits.

The main features of the ZXRE250BW5-7 are its low temperature coefficient, low noise and fast turn-on time. The device features a voltage accuracy of ±1.0% at +25 °C and ±2.0% over the operating temperature range of -40 °C to +85 °C. The ZXRE250BW5-7 has a maximum supply voltage of 5.6V and it can provide an output current of up to 25mA. The device also features a low noise level (0.1mV RMS maximum) and a fast turn-on time of less than 10 microseconds.

The ZXRE250BW5-7 can be used in any application that requires an accurate and stable voltage reference. It is ideal for voltage monitoring circuits, calibrators, A/D converters, power supply monitors and reference voltages. It is also suitable for use in medical systems and automotive electronics. The device is also used in battery operated systems, where the ability to reduce temperature drift is essential.

The main working principle behind the ZXRE250BW5-7 is its use of an internal voltage reference to supply a regulated output voltage. The internal reference voltage is generated by a temperature-compensated Zener diode whose breakdown voltage is precision trimmed to 5.7V. The Zener diode is connected to the output through a resistive divider, which is used to adjust the output voltage level according to the application requirements. The internal negative feedback circuitry monitors the voltage of the output and compares it to the internal reference voltage.

The output voltage is regulated by adjusting the gain of the negative feedback loop until the output voltage is in agreement with the reference voltage. This regulation process is temperature-compensated and automatically adjusts the output voltage over the full range of operating temperatures. The ZXRE250BW5-7 is therefore able to provide a very accurate and stable output voltage.

In summary, the ZXRE250BW5-7 is a precision 5.7V voltage reference designed to provide a very accurate output voltage and to require no external adjustments. The device features a voltage accuracy of ±1.0% at +25 °C, low noise level (0.1mV RMS maximum) and a fast turn-on time of less than 10 microseconds. It is used in a variety of applications, such as voltage monitoring circuits, calibrators, A/D converters, power supply monitors and reference voltages. The main working principle of the device is its use of an internal voltage reference and negative feedback circuitry to maintain an accurate output voltage. It therefore provides a very accurate and stable output voltage.
