Summary An adaptively biased LDO regulator with 0.9V output utilizes a transient-enhanced current mirror. It is stabilized with a 1μF output capacitor and occupies 0.053mm2 in 0.35μm CMOS. It can operate down to VDD= 1.05V when sourcing a load current of 50mA with 99.67% current efficiency while drawing 4.04μA at no load. The output voltage variation is 6.6mVpp when the load is switched between 0 and 50mA with 10ns rise and fall times. ©2008 IEEE.
