ZRC250F03TC

The ZRC250F03TC is a high-performance voltage reference device used in a wide range of application fields, including but not limited to automotive, consumer, industrial, and computer applications. It is classified as a precision voltage reference (PMIC - Voltage Reference) because it provides a very high precision reference signal in the form of a constant regulated voltage. This regulated voltage can be used for a variety of different applications such as powering components, controlling analog-to-digital converters, and providing a stable point for other analogue circuits to reference.

The ZRC250F03TC device consists of two parts: an output node, which is the main section that outputs the reference voltage, and an external compensation network for stability and accuracy. The output voltage is set by the external resistor divider connected to the REF pin. This voltage is then regulated by the internal precision voltage regulator and the output voltage will remain constant even with varying supply and loading conditions. This device also has two additional features – ultra-low dropout voltage and Power-on Reset which allow the reference voltage to remain constant even if the input voltage goes below the rated range.

The working principle of the ZRC250F03TC device is fairly simple but quite efficient. When a voltage is applied to the REF pin, the differential amplifier inside the device amplifies the voltage and sends it to the error amplifier. This amplifies the error and then sends a signal to the PWM circuit to adjust the output voltage accordingly. The output voltage is then regulated by the internal voltage regulator, making sure that the output is always a constant.

The ZRC250F03TC voltage reference is extremely accurate and produces a very stable output voltage. It has a low output voltage noise of 40μVRMS and a high PSRR of 60dB. Apart from its high accuracy and stability, the device is also easy to use and requires minimal external compensation components. It also offers excellent thermal stability as it is specified to keep the output voltage within 1mV over an operating temperature range of -40°C to +125°C. Overall, the ZRC250F03TC is an excellent device for a wide range of applications and is highly recommended for precision voltage reference applications due to its small size and high performance.
