PMIC - Voltage Reference - ZXRE125EN8TA

PMIC (Power Management IC) is a vast family of products used to monitor and control the power supply of a system. Voltage references are an essential part of any PMIC. They serve to provide a stable output voltage regardless of temperature and load. The ZXRE125EN8TA voltage reference, specifically, is a low-power shunt voltage reference optimized for a wide range of applications.

Application Field

The ZXRE125EN8TA voltage reference from Zetex is a low-power device. This makes it suitable for a wide range of applications, including microcontrollers, battery management systems, energy metering circuits, optical power management circuits, and more. In many of these cases, the need for a reliable, low-power voltage reference is paramount. The ZXRE125EN8TA can provide this, while consuming only 0.1μA over a wide operating temperature range.

Working Principle

The ZXRE125EN8TA voltage reference uses a shunt-based topology, which is the most common way to regulate the output voltage. It works by passing a regulated current through a series of components that form a shunt network. The ZXRE125EN8TA specifically uses a ThermalMonitor to control a pair of external resistors to precisely control the voltage across the shunt network. This results in a stable output voltage regardless of temperature and load.

Conclusion

The ZXRE125EN8TA, an ultra-low-power shunt voltage reference, is an excellent choice for applications requiring precise, reliable voltage references. Its low power consumption makes it an ideal fit for a wide range of applications, including microcontrollers, battery management systems, energy metering circuits, optical power management circuits, and more. It’s ThermalMonitor ensures precise voltage regulation while keeping power consumption low.
