Abstract :
A design for a low-power integrated 0.9-V voltage regulator for load currents up to 140 μA is presented. The circuit contains no external components and it stabilizes the voltage of a single battery cell of 1.1-1.6 V with a PSRR >40 dB over a frequency range of up to 30 kHz. The regulating circuit operates a current level and accomplishes automatic load-current limiting. Its r.m.s output noise is <4 μV over a frequency range of 10 Hz-8 kHz. The quiescent supply current is ≈40 μA
