The ZRA125N801TA is a robust low-power CMOS voltage reference that belongs to the PMIC voltage references category. It has been specifically designed to suit high temperature and dual temperature ranges, allowing the device to operate over the full -55°C to +125°C temperature range, while consuming very low power.

This voltage reference device is suitable for different applications, such as voltage and current measurement systems, precision amplifiers, antenna positioner control systems, and power supply stability. It also provides a high degree of accuracy, stability, and low temperature drift, making it an ideal choice for high-precision applications.

The ZRA125N801TA has a 2.5V nominal output voltage and is designed to handle up to 120mA in continuous mode and 500mA for transient applications. It exhibits excellent line and load regulation, with a low output impedance. The device also features a wide operating temperature range from -55°C to +125°C.

The operating principle of the ZRA125N801TA is based on a voltage regulator, which is used to maintain a steady output voltage across a wide range of changing temperatures. The voltage regulator consists of a power transistor, which is connected in series with a diode. The diode improves the performance of the circuit by providing a voltage drop of 0.6V in the circuit. The power transistor is also connected to the input terminal of the device, which is connected to the Vcc pin. The output terminal, which is connected to the output pin, is connected to the collector of the transistor. A feedback loop is then formed to ensure the output voltage of the device remains the same regardless of any change in the surrounding temperature.

The ZRA125N801TA is a highly reliable and accurate voltage reference device. It features a wide operating temperature range and provides a high degree of accuracy and stability. This makes it suitable for use in high-precision applications and allows it to deliver beneficial performance in voltage and current measurement systems, precision amplifiers, antenna positioner control systems, and power supply stability.
