The ZRC500F01TC voltage reference is a type of Programmable Integrated Circuit (PMIC) designed to provide accurate voltage references for the development of circuit boards and systems. The device is constructed using the latest process technology intending to deliver improved performance and reliability. It offers superior accuracy, temperature stability and transient response, while maintaining low output voltage noise and low power consumption.

The ZRC500F01TC has a wide range of applications and working principles and can be used in devices as varied as optical transceivers, embedded systems, medical imaging, power and energy management, A/D and D/A converters and more. The device offers an adjustable low-side voltage reference, capable of operating from 0.5 to 4.5V customizable output voltages, to achieve the desired accuracy and temperature coefficient specifications.

The device consists of several analog blocks which include the reference source, the adjustment network, the output driver and circuitry for compensation and temperature control. The reference source generates a highly accurate and low-noise initial voltage level and supplies this to the adjustment network. The adjustment network consists of precision resistors that implement an adjustable voltage divider that receives a reference signal from the reference source and supplies a custom output voltage at the output pin.

The control loop of the ZRC500F01TC keeps the output reference voltage constant and its characteristics in the presence of output current and temperature changes. The output driver is designed to provide robust and stable output voltage. Additionally, the device offers an auto-compensation feature which enables lower external component count and reduces the time for developing hardware and setting up the loop for optimum stability.

The device has various features which offers multiple benefits to the user. It provides accuracy and stability from -40°C to +125°C by optimizing the voltage reference. The current limit feature allows the device to be protected against current spikes generated by unexpected load conditions. Active reverse current protection prevents back bias current flow through the device during destructive conditions. The open connection detection allows the controller to detect if there is an open connection between the ground and the reference output, and forces the output reference voltage to a safe DC value.

The ZRC500F01TC is Ideal for customers who are looking for more performance and energy efficiency from their PMIC Voltage Reference solution. The device has a wide range of operating temperature range and features that provide a robust and reliable solution for most industrial and consumer applications.
