Abstract:
An integrated circuit including a low drop out (LDO) regulator configured to implement transient response and loop stability in a capacitor-less configuration, including an error amplifier configured to receive a bandgap reference input; first and second pass elements configured to receive outputs from the error amplifier; first and second resistor feedback networks, the first resistor network configured to provide a feedback output as an input to the error amplifier; an overshoot protection circuit; and an output connected to the pass transistors; wherein the capacitor-less low dropout (LDO) regulator is operable without an output capacitor.
