Its PSRR spans 85dB at 10Hz down to 50dB at 1MHz, meaning it attenuates low-frequency ripple from upstream switching converters and still holds 50dB rejection well into the MHz band where many LDOs roll off sharply. Maximum dropout is 0.2V at the full 350mA load, so a 2.0V input rail provides the necessary headroom. The quiescent current is 38µA typical, rising to 80µA maximum supply current — low enough for always-on or battery-powered sections where the regulator itself must not dominate the idle budget. ## Package, temperature grade, and protection Housed in a 5-DSBGA package (0.96x1.33mm) with a 6-bump UFBGA footprint, the part is suited for space-constrained portable or module designs. Built-in protection includes over-current, over-temperature, and under-voltage lockout (UVLO). An enable pin allows external on/off control, letting the system power down the LDO when the rail is not needed.","metaTitle":"TPS72018YZUR LDO 1.8V 350mA DSBGA, PSRR 85dB","metaDescription":"TI TPS72018YZUR linear regulator, fixed 1.8V output, 350mA, PSRR 85dB~50dB (10Hz~1MHz), 5-DSBGA package.
