Power management integrated circuits (PMIC) provide the necessary power circuitry for a variety of electronic devices. Voltage references are a critical type of PMIC that are used to provide a stable and reliable reference voltage. ZRC250A03STOA is a voltage reference PMIC that is designed to provide a stable and reliable voltage reference output with excellent temperature stability and low noise characteristics. It is optimized for low power applications and is suitable for battery-powered equipment.

The ZRC250A03STOA is a low noise, low cost voltage reference with an output voltage of 250mV. It is designed to be used in communication and data acquisition applications, where a low noise reference is required. The device is packaged in a miniature 8-pin SOIC package and operates from a voltage range of 1.7 to 5.5V. The ZRC250A03STOA offers excellent temperature stability with a ±0.5mV/°C max temperature coefficient. Additionally, it features low output noise of 0.08vrms (max) over a wide frequency range (up to 1kHz), making it suitable for precision analog and digital applications.

The ZRC250A03STOA works by creating a steady voltage reference from an external series resistor and a resistor connected in parallel with the external resistor. This creates a negative feedback loop which ensures that the voltage reference output remains stable as the operating temperature and supply voltage changes. When the reference voltage is set correctly using the external resistor, the output voltage remains within the tolerances of the reference voltage. The design also reduces noise, voltage drops, and temperature drift. Input-referred noise of the ZRC250A03STOA is typically 0.29µVrms (max).

The ZRC250A03STOA is a low-cost, stable, and reliable voltage reference ideal for a wide range of applications. It is suitable for use in communication and data acquisition applications where low noise is required. The device features excellent temperature stability, low noise, and a low power consumption, making it an ideal solution for battery-powered devices. The simple two-terminal configuration and integrated design make it easy to use and integrate into existing systems.
