Understanding noise in linear regulators

Focus:

Factors such as the bandgap reference, the resistor divider, and the input stage of the op amp determine the output noise of low dropout linear regulators (LDOs).

What you’ll learn:

• How to understand the factors that determine the output noise in low dropout linear regulators (LDOs)
• How to reduce output noise in low dropout linear regulators (LDOs)
• How to compare noise specifications of different LDOs
