The integrated noise value is derived from the integral of the noise spectral density function. However, it is very complicated to use a function to represent any curve and integrate it. It is easier to divide the measurement curve into small parts. If the frequency difference of each part fn+1 – fn tends to 0, the sum of all contributions is equal to the integral of the function. 
High output capacitance values, such as 10 uF, improve transient response. Better transient response may be one reason for using high output capacitor values. In this example, the NCP110 has ringing (more than one undershoot) and a longer settling time to transient events when using a higher output capacitance value, but it is still stable. The ringing increases the peak value and the integrated noise also increases, as shown in the following table. The NCP110 LDO regulator is designed for a lower output capacitance of 1 uF. The additional capacitance improves the transient response of the system, but affects the noise performance of the system. 
At the beginning of the company's establishment, the business philosophy of "focus on intelligent manufacturing and dedicated service" was determined. The management has been continuously optimized and obtained the ISO9001 quality management system certification issued by the British Royal Authorized Organization SIRA; the products have respectively obtained VDE, UL, ENEC, SAA, KC, PSE, TUV, ASTA, SASO, CQC and other international safety certifications. Set up a professional testing laboratory to ensure the stability and improvement of quality under efficient production, so that product services can be brought to a higher level.
Guangdong Oujun Technology Co., Ltd. will take "continuous innovation, customer first" as its tenet, scientific management as the guide, full monitoring and tracking service, and be your best quality supporting supplier.
We sincerely look forward to working with the vast number of domestic customers to join hands in a win-win situation and create development together!
What is integrated noise? the second part
Previously in the blog "What is LDO noise? In the first part, we talked about what noise is, how to classify it, and introduced the ultra-low noise low-dropout regulator provided by ON Semiconductor. Today, we will talk in further detail about what is integrated noise.
