LDO basics: Power Supply Rejection Ratio (PSRR)

描述

2018年 4月 2日
This video will go over what Power Supply Rejection Ratio (PSRR) is and will explore an application in which one can calculate the PSRR. The PSRR calculations follows a formula in which one can find the values to the equation either from the electrical characteristics or from the PSRR versus frequency plot provided in the data sheet. The importance of output capacitors and the difference between the input voltage and output voltage will be discussed as these parameters can affect the PSRR value.
