摘要:

This paper presents a low-drop (LDO) linear regulator with buffer impedance attenuation (BIA) for frequency compensation. This novel proposed LDO take advantage of the dynamically-biased shunt feedback in the buffer stage, which could lower its output resistance for driving the pass device to achieve fast response. Implemented in 0.35μm CMOS process, the LDO dissipates 184A quiescent current and is able to deliver up to 100mA load current. With a 2.3μF output capacitance, the maximum transient-output variation is 25mV with full-load step change of 100mA. The proposed circuit will find application in the battery-powered portable devices. © 2012 IEEE.
