LDO basics: Dropout voltage
2018年 4月 2日
This video will go over what an LDO is and discuss the importance of dropout voltage in an LDO. An application will demonstrate the importance of dropout voltage when designing as dropout voltage can affect the desired output of an LDO. The designer must keep the input voltage and dropout voltage in mind when using an LDO. Furthermore, PMOS and NMOS architectures used in LDO's will be covered as this has the most impact to the dropout voltage. The video will also show other variables such as pass element size, temperature, output current, temperature, and output accuracy that all can affect dropout voltage.
