PMIC - Voltage Reference are used to provide precise reference voltages, benchmark adjustable voltages and multiple low voltage identical output from a single device. ZRA124F01TC is a device from this class, designed to provide a more precise, few parts and cost-effective solution for many reference applications.In most cases, its application field and working principle reflect the functions and performance required for achieving the reference voltage needed. Let\'s take a look at what features ZRA124F01TC offer and how those features enable this device to provide precise reference voltages.

ZRA124F01TC is a 4-pin device that integrates a voltage reference, shunt regulator and a voltage comparator. It comes with a 0.7 V~6.0 V range output voltage and a minimum temperature coefficient of 0.1 ppm/°C. It also has a wide operating temperature range from -65°C to 125°C. These features enable the device to provide a low-current reference voltage perfectly suitable for microcontrollers, FPGA, and ASICs with power supply requirements.

The working principle of the device involves the use of an ultra-low drop-out voltage reference to obtain the reference voltage. This reference voltage is then amplified and compared with an internal reference signal generated from the shunt regulator. The output of the comparator determines the voltage regulator output. Since this reference voltage is extremely small and highly accurate, it can accurately provide a stable reference voltage output even when the input supply voltage changes.

The device also has several features to enable it to provide precise reference voltages. For example, it has a high-accuracy Voltage Reference input pin to obtain a precise output voltage. The current and voltage regulator can also be externally limited to provide a reliable and consistent reference voltage. Additionally, the reference voltage can be offset by adjusting the gain control pin.

Other features of the device include low EMI/RFI noise, Output disconnect switch, Guard ring for EMI/RFI suppresion, and a Thermal shutdown protecting from temperature overloads. All these features make ZRA124F01TC a perfect choice for achieving precise reference voltage outputs, as it is designed to minimize power dissipation, noise, and any related accuracy problems.

In summary, ZRA124F01TC is a versatile and highly accurate voltage reference device, ideal for providing accurate reference voltages for a wide range of applications. It can easily integrate in microcontrollers, FPGA, and ASICs and its features enable it to provide a precise and cost-effective solution for many reference voltage requirements.
