PMIC - Voltage Reference technology is a common engineering application. It is used to control the voltage of a power supply. It is often used in multiple applications such as industrial, automotive, computer, and consumer electronics. The ZR40402R41STOA is one of the most popular voltage reference products available today. It is known for its high accuracy and reliability. In this article, we’ll discuss the application field and working principle of the ZR40402R41STOA.

The ZR40402R41STOA is a floating current regulator, which is a type of Voltage Reference technology. This type of regulator is ideal for applications where a system requires several fixed input voltage and current levels. The regulator provides a stable voltage and current, which allows accurate control and regulation of the system\'s power supply. This is especially useful in applications that require a steady power supply and consistent voltage levels.

The ZR40402R41STOA is designed to provide a high-accuracy reference voltage of 2.5 V (±1%) at temperatures between -25°C to +85°C. This allows it to be used in various temperature environments. The device features a low operating current of 0.1 mA, making it highly suitable for battery-operated applications. Additionally, the device has a maximum load regulation at 5 mA and a minimum 0.4µA bypass current, helping save battery power.

The device is also designed to offer an improved accuracy of 1.2% over temperature range and low dropout voltage of 250 mV. Furthermore, it also offers a high power supply rejection of 80 dB. This makes the device ideal for applications where low-noise operation is required. It is typically used in industrial instrumentation, medical instruments, industrial lighting, automotive electronics and consumer products.

The ZR40402R41STOA device uses a charge pump circuit to achieve its high accuracy and low dropout voltage. The circuit consists of a main booster circuit and a secondary oscillator circuit. When the main booster circuit is supplied with the correct input voltage, it amplifies the input voltage and generates an alternating output voltage which is used to charge the oscillator circuit. The oscillator circuit then generates an oscillating output voltage, which is applied to the voltage regulator. The voltage regulator provides a stable reference voltage at its output. The output of the voltage regulator is further amplified by the main booster circuit to a higher level, ensuring a high-accuracy reference voltage.

In summary, the ZR40402R41STOA is a popular PMIC - Voltage Reference product. It is ideal for applications where a system requires multiple fixed input voltage and current levels as it provides a stable voltage and current with high accuracy and reliability. It is typically used in industrial instrumentation, medical instruments, industrial lighting, automotive electronics and consumer products. The device uses a charge pump circuit to achieve its high accuracy and low dropout voltage.
