The SOT-23-5 package (SC-74A, SOT-753) keeps the footprint small for space-constrained power rails on sensor nodes, wireless modules, or MCU core supplies. ## Dropout and PSRR at the load PSRR holds at 52dB from 1kHz through 1MHz, meaning upstream switching noise in that band is attenuated by a factor of ~400 before reaching the load. For a 3.3V rail feeding a 3V LDO, the 300mV headroom is tight but workable if the upstream regulator's dropout and line regulation are accounted for. Quiescent current is 40µA max — the regulator's own draw is low enough for battery-powered designs that spend most of their time in sleep, though the 1A output capability is sized for active bursts rather than continuous high current. ## Protection and control Built-in current limit, thermal shutdown, and undervoltage lockout (UVLO) protect the load and the regulator against fault conditions. The Enable pin allows the output to be gated by a logic signal — useful for sequencing rails or shutting down the regulator in low-power standby modes.","metaTitle":"Texas Instruments TLV75730PDBVR LDO, 3V Fixed, 1A, SOT-23-5","metaDescription":"Texas Instruments TLV75730PDBVR LDO, 3V fixed output, 1A, 52dB PSRR (1kHz-1MHz), SOT-23-5.

This means switching noise from a buck converter upstream is attenuated by roughly 400x in that frequency band — critical for powering sensitive analog loads like ADCs or RF front-ends where ripple on the supply rail couples into the signal path."},{"question":"What package does TLV75730PDBVR come in?","answer":"The TLV75730PDBVR is supplied in an SOT-23-5 package (also designated SC-74A, SOT-753).
