PMIC - Voltage Reference

Voltage reference is a vital element of today’s power management integrated circuit (PMIC) designs. ZRC400A02STOB is an 800 mV precision 3-terminal voltage reference for advanced PMIC applications. This device is designed to provide an ultrasmall footprint and low-power consumption solution for reference voltage needs.

Application Field

ZRC400A02STOB is designed for voltage reference needs in advanced PMIC applications. It is suitable for applications such as portable equipment, household appliances, industrial control systems, and automotive electronics. With an ultra-small footprint and low-power consumption, this device helps designers to reduce board space and lower the overall energy consumption of the system.

Working Principle

ZRC400A02STOB voltage reference utilizes a bandgap reference circuit combined with temperature compensation to provide a highly stable reference voltage. The reference voltage is set by the designer, between 600 and 1000mV. A thermal locking loop and temperature compensation circuitry ensure the reference voltage is accurate to within 0.3% over the entire operating temperature range. The output of the reference voltage is a steady 800 mV, with very low power consumption.

Features

ZRC400A02STOB voltage reference comes with several advantages and features that make it ideal for PMIC applications. These include:

• Ultra small footprint – 0.8 x 0.8 mm
• Accurate reference voltage – 0.3% over operating range
• Low power consumption – 2 mW
• Wide operating temperature range – -40°C to 125°C
• Low quiescent current – 0.6 uA
• High capacitive load drive capability – 10 pF

The internal architecture of the device features an adjustable bandgap reference core with a laser-trimmed resistor network that uses a temperature tuned, auto-pointing temperature compensation loop. This ensures an accurate output voltage over temperature and consistently low-power consumption.

Conclusion

ZRC400A02STOB Open-Drain Voltage Reference is an ideal choice for advanced PMIC applications where precision and reliability are paramount. With its simple, three-terminal configuration, ultra-small footprint, and low-power consumption, this device provides a great solution for designers looking to reduce overall system cost and energy usage.
