It takes an input up to 5.5 V and delivers a regulated 3.3 V rail with a maximum dropout of 0.27 V at full load. The enable pin lets you gate the output for sequencing or power-save modes. Protection features — current limit, thermal shutdown, and UVLO — are built in, so no external supervisor is needed for basic fault coverage. ## PSRR profile — where it helps and where it doesn't PSRR is 68 dB at 100 Hz, dropping to 28 dB at 100 kHz. That means it knocks down line-frequency ripple and its harmonics well, but above a few hundred kHz the rejection rolls off. If your rail feeds an RF PA or a high-speed ADC with switching noise above 1 MHz, you'll want a post-filter or a regulator with a higher-frequency PSRR floor. For audio codecs, sensor analog supplies, or MCU analog blocks running from a switching pre-regulator, this part cleans up the rail adequately. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window is in effect. The part is ROHS3 compliant.","metaTitle":"TLV74333PDQNR 3.3V 300mA LDO, PSRR 68dB, 4-X2SON","metaDescription":"TI TLV74333PDQNR fixed 3.3V output LDO, 300mA, 0.27V dropout, PSRR 68dB~28dB (100Hz~100kHz), 60µA Iq, -40°C~125°C, 4-X2SON.
