The fixed output eliminates the external resistor divider, saving two components and one feedback node on the PCB. Its PSRR profile — 68 dB at 100 Hz rolling off to 28 dB at 100 kHz — means it attenuates low-frequency ripple from a switching preregulator well, but above 100 kHz the attenuation drops enough that the upstream converter's switching noise may couple through unless the layout keeps the input trace short and the bypass capacitor close. The 60 µA quiescent current keeps the regulator's own draw low in always-on subsystems, though this is not an ultra-low-Iq part for microamp-level sleep modes. ## Temperature grade and protection set The 125°C TJ ceiling means the output current must be derated above about 85°C ambient depending on the board's thermal resistance. Built-in protection includes over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO). The UVLO prevents the output from turning on until the input rail is above the internal threshold, avoiding a brown-out start into a heavy load. The part comes in a 4-XDFN exposed pad package, also designated as the 4-X2SON (1x1 mm) supplier device package. The 0.29 V dropout at 300 mA means at full load the input must stay above 3.29 V, and the power dissipation (about 87 mW at 300 mA with 3.29 V in) is manageable on a standard two-layer board with a small copper pour. No stock-holding claim; each order is verified against the BOM quantity.","metaTitle":"Texas Instruments TLV73330PDQNT LDO, 3V Fixed 300mA, 4-X2SON","metaDescription":"Texas Instruments TLV73330PDQNT LDO, 3V fixed output, 300mA, PSRR 68dB~28dB (100Hz~100kHz), -40°C~125°C, active production, ROHS3.
