REF02HZ: Voltage Reference PMIC Application Field and Working Principle

The REF02HZ is a precision voltage reference PMIC (Power Management Integrated Circuit) designed to produce highly precise output voltages while consuming very little power. It is ideal for use in systems with high performance requirements and tight power budgets. This voltage referencePMIC can be used in a variety of applications, including test and measurement, DAC (Digital to Analog Converter) calibration, and power monitoring.

Overview of REF02HZ

The REF02HZ is an analog voltage referencePMIC that offers superior accuracy, stability, and reliability in a very small package. This linear voltage referencePMIC operates over an input voltage range of 2.5V to 7.0V, allowing it to be powered from a variety of sources including batteries, USB, or AC power. The REF02HZ is available in a space-saving 14-pin SOIC (Small Outline Integrated Circuit) package that measures just 0.20" X 0.30" (5.1mm X 7.6mm). This makes it ideal for applications that require a small form factor. The REF02HZ operates over the temperature range of -40°C to +85°C and is rated for an operating lifetime of up to 10 years.

Precise Output Voltage

The REF02HZ operates using a bandgap circuitry inside the device to precisely generate a stable voltage reference. This precision voltage referencePMIC offers a temperature coefficient of 36ppm/°C, making it ideal for applications with stringent accuracy requirements. The REF02HZ offers a very precise output voltage of 10.000V - 10.0199V with a tolerance of ±0.1mV. In addition, the REF02HZ offers a very low line regulation of 0.05%, which make it ideal for applications requiring accurate and stable output voltages even in highly varying power supply conditions.

Low Power Consumption

The REF02HZ is designed to offer excellent power efficiency with low power consumption. This voltage referencePMIC draws a typical quiescent current of just 120μA, allowing it to be used in power-sensitive applications. This quiescent current can be further reduced with an external resistor, allowing the REF02HZ to achieve a typical quiescent current of just 30μA. The REF02HZ also offers very low output noise of just 2mV, allowing it to generate cleaner signals for sensitive applications such as sensor interfacing.

Applications for REF02HZ

The REF02HZ is designed for use in a wide range of precision voltage reference applications including:

• Test and measurement
• DAC (Digital to Analog Converter) calibration
• Precision power monitoring
• Portable power supply design
• Lighting systems
• Analog signal conditioning
• Intelligent home and industrial automation

Conclusion

The REF02HZ is an ideal voltage referencePMIC for applications requiring a precise output voltage with low power consumption. This precision voltage referencePMIC offers a wide operating temperature range and long-term device reliability as well. The REF02HZ is suitable for a variety of applications, including test and measurement, DAC calibration, and power monitoring.
