Abstract

Power management is necessary to reduce the standby power of portable electronics such as cellular phones, pagers, laptops, etc. The LDO (low-dropout regulator) is one of the most popular DC-DC converters widely used in power management and the demand for LDO is increasing by the growing demand for their applications. For Li-Ion battery of portable devices the input voltage generally varies from 2.7V to 4.2V, this paper demonstrates a 59mA LDO with input voltage operating from 2V to 3.52V. Simulated in 0.35μm CMOS technology, the LDO only use 1Ω effective series resistance (ESR). With a 2.3μF output capacitor and quiescent current 56μA, the maximum transient-output variation (overshoot voltage) is 58.98mV with full-load step change of 59mA.
