Protection features include over-current, over-temperature, short-circuit, and UVLO. ## Quiescent current and battery-operated duty Quiescent current is 60 µA typical — low enough for always-on domains in battery-powered gear, though not the sub-1 µA class of dedicated nano-power LDOs. The fixed 3.3 V output eliminates external feedback divider resistors.","metaTitle":"Texas Instruments TLV73333PDQNT LDO, 3.3V, 300mA, 4-X2SON","metaDescription":"Active LDO regulator, fixed 3.3V output, 300mA, 60µA quiescent current, 4-X2SON package.
