Power management and control functions are critical components of virtually any electronic device. Voltage references play a key role in regulating power in electronic systems, ensuring that the voltage levels are consistent and stable to ensure the smooth operation and the longevity of the electronic device. The ZR404005R25STOB is a voltage reference, part of the extended range of voltage references in the Power Management Integrated Circuit (PMIC) product range. It offers bipolar output voltage reference stability over temperature and PVT.

The ZR404005R25STOB is a low power precision voltage reference designed to provide high linearity, low noise, low drift and low temperature coefficient for use in Instrumentation, measurements and data acquisition systems. The device offers output currents from 2 to 15mA, with an initial tolerance of ±2mV and a temperature coefficient of ±25ppm/°C. The device is capable of achieving supply voltage ranges from 2.3 to 5.5V. It also features an adjustment pin that allows for a ±100mV adjustment range. This feature allows users to adjust the output voltage to suit their application precisely.

The ZR404005R25STOB is best suited for systems that require tight output voltage regulation, with minimum noise and temperature drift across a wide temperature range. The device is mainly applicable in precision measurement devices where the output voltage needs to remain stable even during environmental stress such as temperature and voltage variations. Typical applications include precision current sources, bridges resistors, voltage dividers, reference circuits, data acquisition systems, digital and analog measurements, medical instruments, lighting systems, smart meters and battery management systems.

The ZR404005R25STOB works on the principle of Zener breakdown for consistent and precise voltage reference across a temperature range and PVT (Process, Voltage and Temperature) variations. This is achieved by using a junction-based voltage reference characterized by a reverse breakdown voltage. The device can achieve tight regulation accuracy at temperatures from -40°C to +125°C. The device offers a high accuracy of ±2mV and excellent temperature-induced stability.

In summary, the ZR404005R25STOB is a precision voltage reference designed for powering precise instruments and other applications which require good load regulation and low temperature variations. Its features make it suitable for systems requiring linearity and accuracy over a wide temperature range, such as medical instruments, measurements, data acquisition systems and smart meters. Its adjustment pin allows precise adjustment of the output voltage, providing users with a high degree of flexibility and control.
