Abstract
A transient response accelerated (TRA) low dropout (LDO) regulator has an error amplifier having a feedback input, and a reference input configured to receive a reference voltage, and an output that controls a pass gate. The pass gate output voltage is applied to the feedback input. A transient response accelerator (TRA) circuit detects a rapid voltage drop on the pass gate output and, in response, applies a pulse control that rapidly lowers the resistance of the pass gate.
