Abstract :
An integrated low-noise, high power supply rejection ratio (PSRR), low-dropout (LDO) linear regulator has been developed in Texas Instruments´ (TI) 130nm CMOS technology. The LDO regulator is capable of producing a regulated output voltage of 2.8 V from a Li-ion battery supply, with a dropout voltage of 200 mV while supplying a load current of 150 mA. The LDO regulator features > 65 dB PSRR at 20 kHz, and > 40 dB up to 1 MHz. The LDO regulator also features output noise performance of < 350 nVrms/radicHz at 100Hz. The LDO die area is 0.166 mm2 and the maximum no-load power consumption is 450μW.
