Voltage references, such as the REF5010ID, are important components of power management integrated circuits (PMICs). They provide a known, stable output reference voltage to other components within the circuit, allowing the overall system to operate accurately and efficiently. In this article, we will discuss the REF5010ID application field and its working principle.

The REF5010ID is a low-power micro-power, temperature-compensated voltage reference designed for use in battery-powered systems. It has a maximum supply current of 6μA and can provide an output voltage ranging from 0V to 3.2V. This makes it suitable for applications such as power saving, data converters, portable communications, and microcontroller-based systems. The REF5010ID is packaged in a small thermally-enhanced 8-pin SOIC, making it suitable for space-constrained applications.

The REF5010ID reference works by using a combination of temperature-compensating circuitry and a low-power IC to stabilize the voltage reference. The IC includes a bandgap reference that is temperature compensated using a resistor-divider network. This network serves to adjust the reference voltage to compensate for temperature changes in the ambient environment. The IC then feeds the reference voltage via output pins to the circuit being monitored. A capacitor, usually connected at the output, acts as a low-pass filter and removes any ripples from the output voltage.

The REF5010ID is designed to operate over a wide range of temperatures, up to 125°C, making it suitable for automotive and other extreme temperature environments. It also features an internal voltage regulator, allowing it to provide a stable output voltage under varying supply voltage conditions. This makes it ideal for low-power systems, such as portable devices, where stable power supply is critical. Additionally, the REF5010ID is also designed to be ESD protected, making it suitable for use in harsh, high-noise environments.

In summary, the REF5010ID is a low-power reference voltage ideal for use in battery-powered systems. It has a wide temperature range of operation and includes temperature-compensating circuitry and a low-power IC to provide a stable output reference voltage. The REF5010ID is packaged in a small thermally-enhanced 8-pin SOIC and is also ESD protected, making it suitable for use in a variety of applications.
