Abstract
A design for a low-power integrated 0.9-V voltage regulator for load c urrents up to 140 muA is presented. The circuit contains no external c omponents 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. Th e regulating circuit operates a current level and accomplishes automat ic load-current limiting. Its rms output noise is < 4 muV over a frequ ency range of 10 Hz-8 kHz. The quiescent supply current is almost-equa l-to 40 muA.
