A new low-power LDO chip: It's current is 9µA on no-load

When the portable electronic devices work, the powers always change in large range. To ensure the normal operation of electronic equipments, we design a new low-power low-dropout regulator (LDO). The chip is fabricated on the CSMC 0.5 μm CMOS technology. The Line Regulation is 0.08%. The PSRR is 44.34 dB. The current is 9 μA on no-load. It has the low static power loss, low dropout voltage, merits and so on. The chip occupies an area of 1.02mm × 1.02 mm including 82 transistors.
