Abstract :
This paper presents an ultra-low quiescent current output capacitor-less Low-dropout (LDO) regulator with a novel slew-rate-enhanced (SRE) circuit. By adopting the novel SRE circuit, the transient response of the regulator was improved apparently. Simulation results show that, the LDO regulator consumes a quiescent current of only 930nA at steady state.
