A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...

Stable regulation of output voltage is an operational imperative of linear regulators. While this topic has been discussed in the past (Reference 1 and Reference 2), this article provides a practical, ...
