In this paper, we present the design of a 4.5 V low dropout (LDO) voltage regulator implemented in the 130 nm CMOSprocess. The design uses a two-stage cascaded operational transconductance amplifier (OTA) as an error amplifier, with abody bias technique for reducing dropout voltages. PMOS is used as a pass transistor to ensure stable output voltages. Theresults show that the proposed LDO regulator has a dropout voltage of 32.06 mV when implemented in the130 nm CMOSprocess. The power dissipation is only 1.3593 mW and the proposed circuit operates under an input voltage of 5V with anactive area of 703 μm2, ensuring that the proposed circuit is suitable for low-power applications.
