PMIC - Voltage Reference is an important type of electronic components used in many electronic systems. It can provide precise voltage reference signals, so as to ensure that each circuit element of the electronic system can accurately and reliably detect and measure the voltage of the power supply or signal. The Ref198ESZ-REEL is one of the most widely used voltage reference ICs in the industry.

The Ref198ESZ-REEL consists of an integrated circuit containing precision voltage reference and a buffer amplifier. The reference voltage is up to 5V and the output voltage is stable and the temperature coefficient is low. The circuit also includes a voltage comparator and a protection circuit. This helps the IC to match other ICs and maintain the precise required voltage reference.

The applications of Ref198ESZ-REEL can be found in many fields. It is used as an essential reference voltage source in data converters, signal conditioning, power supplies, microprocessors and memory systems. It can also be used as an input reference for monitoring circuits, improving the accuracy of signal transmission and processing, or as a voltage reference for high-speed electronic signal conversion or signal processing.

The working principle of the Ref198ESZ-REEL is based on the principle of temperature coefficient compensation. The temperature coefficient of the voltage reference is very small and its output voltage is very stable. The output voltage of the IC with temperature coefficient compensation is independent of the temperature, thus achieving greater accuracy.

The circuit of the IC consists of voltage reference, voltage comparator, overvoltage protection and other components. The voltage reference is the core factor in determining the output voltage of the IC. The voltage reference consists of two reference input circuits and a bridge. When the voltage applied to the bridge is insufficient, the bridge output voltage drops and the IC increases its output voltage to maintain its reference voltage until the required voltage is reached. The comparator is used to compare the input voltage with the reference. When there is an overvoltage, the IC shuts down by triggering the protection circuit.

In summary, the Ref198ESZ-REEL is one of the most widely used voltage reference ICs in the industry. It can provide reliable, precise voltage reference signals, be used in a variety of fields and makes the reference voltage independent of temperature and other parameters. Its circuit consists of voltage reference, voltage comparator, overvoltage protection and other components and it works on the principle of temperature coefficient compensation.
