Low drop-out (LDO) regulators developed back in the age when large-capacitance multi-layer ceramic capacitors (hereinafter, MLCCs) were uncommon cause a phase delay, leading to oscillation when connected to a low-ESR capacitor like an MLCC...
The loss in linear regulators increases as the difference between the input and output voltages increases. Since most of the loss is converted to heat, a very large amount of heat may be generated in some conditions...
When a linear regulator IC is turned ON, the electric charge is stored in the output capacitor and the output voltage increases up to the specified value.
This application note proposes a circuit using an output ceramic capacitor that allows a stable phase compensation.
This application note introduces a method for easily measuring the phase margin with a Frequency Response Analyzer (FRA) made by NF Corporation.
Provides some hints on how to connect LDOs in parallel.
