A voltage reference is an electronic component or device used to provide a reference voltage for other electrical devices or systems. The REF3125AIDBZRG4 is a micropower reference IC (integrated circuit) designed for low-voltage, low-power applications. It has a low quiescent current of less than 10 micro-amps. It is available in a 3-lead SOT-23 package and is rated for operation over a temperature range of -40°C to 125°C.

Application Field of REF3125AIDBZRG4

The REF3125AIDBZRG4 provides a stable, low-power, Precision Bandgap Reference Voltage (stable at both high and low temperatures). Its low quiescent current makes it an ideal solution for Very Low-Power applications, such as battery-powered applications. It can provide a voltage reference for a variety of precision circuits, such as analog-to-digital converters, digital-to-analog converters, logarithmic amplifiers, digital isolators, analog amplifiers, and sensors.

The REF3125AIDBZRG4 is also suitable for low-voltage power supply monitoring and low-power LED drivers. It is extremely useful in portable devices, where circuit power consumption needs to be kept to a minimum. It is also ideal for use with precision logic and timing circuits, such as real-time clocks and microcontrollers.

Working Principle of REF3125AIDBZRG4

The REF3125AIDBZRG4 uses a precision bandgap architecture to generate a precise voltage reference over a wide temperature range. It combines a temperature-compensated Zener diode and an external PMOS transistors in a single package. The reference voltage is generated by measuring the voltage drop across the temperature-compensated Zener diode, and then adjusting the current through a PMOS transistor.

The voltage reference is adjustable over a wide range from 0.8 V (low voltage limit) to 6 V (high voltage limit). The IC also features a low-impedance output buffer. The output buffer is designed to maintain a tight voltage regulation even in the presence of large transients.

The REF3125AIDBZRG4 requires only a single external resistor and one decoupling capacitor to operate. The reference voltage is provided at two different voltages, one for positive and one for negative polarity. The IC also has a power-on reset output, which is active low when the voltage reference is below its low voltage limit.

Conclusion

The REF3125AIDBZRG4 is a micropower reference IC designed for low-voltage, low-power applications. It provides a highly accurate voltage reference over a wide temperature range. Its low quiescent current makes it ideal for very low power applications, such as battery-powered devices. Its low-impedance output buffer makes it perfect for use with precision logic and timing circuits. The IC requires only a single external resistor and one decoupling capacitor for operation.
