PMIC - Voltage Reference

REF01EZ is a precision voltage reference IC. It provides users with accurate and stable voltage outputs for use in various applications. The REF01EZ is designed for ease of use and high accuracy at a low cost.

The REF01EZ is a monolithic integrated circuit that combines three tightly matched, prime-grade P-type and N-type MOS transistors and a high-precision temperature-compensated voltage reference into a single package. It provides an output voltage of 1.23V to 10V, with an accuracy of 0.1%, at temperatures of 0°C to 70°C. The device can supply up to 10mA of load current, and has a low output noise of 20μV Peak-to-Peak and a high dynamic range. The REF01EZ also provides high-precision temperature compensation and low current consumption (1mA).

The REF01EZ is suitable for use in a wide range of applications such as precision instrumentation and control, data acquisition, ADC and DAC reference source, system power management circuits, systems requiring voltage reference, and reference for an A/D application. It can also be used in medical, laboratory, and industrial applications. The REF01EZ is used in an increasing number of consumer electronics applications such as TV sets, DVD/Blu-ray players, cellphone/smartphone chargers, and stereo systems.

The working principles of the REF01EZ are based on the theory of static electricity. An electric field is applied across two oppositely charged surfaces of a material, such as a pair of metals or a semiconductor. This electric field produces a voltage across the two surfaces due to the difference in potential between them. This voltage is referred to as the “static voltage”. The REF01EZ uses the static voltage to generate an output voltage that is stable and accurate even in the face of varying temperatures.

The REF01EZ employs an internal temperature-compensated zener reference that is connected to two transistor-based voltage references. This arrangement enables the output voltage to remain accurate regardless of its ambient surroundings. The REF01EZ also employs current-limiting circuitry prevents current overloads and maintains a stable output. In addition, the REF01EZ features a low-noise, low-drop-out design that ensures minimal output deviation.

The REF01EZ is a cost-effective, reliable and reliable voltage reference IC that can be used in a variety of applications including precision instrumentation, data acquisition and A/D conversion, system power management, and a host of consumer applications. This device offers a wide output voltage range, a high level of precision and low power consumption, making it ideal for many applications requiring an accurate and stable voltage reference.
