The 0.3 V maximum dropout at full load means the input must stay above 3.6 V to keep the output in regulation — a 3.6 V or 5 V rail provides comfortable headroom; a 3.4 V rail does not. Quiescent current is 385 µA typical — not an ultra-low-Iq part for always-on battery nodes, but acceptable for continuously powered analog rails where the regulator's own draw is a small fraction of the load current. Power-supply rejection ratio is 70 dB at 1 kHz, which attenuates a 1 Vpp ripple on the input to roughly 0.3 mVpp at the output — useful for cleaning up a switching regulator's residual noise before feeding a precision ADC or op-amp reference pin. ## Package, temperature grade, and protection — board-fit details Housed in an SC-74A / SOT-753 package (supplier device package SOT-23-5), the part occupies a compact footprint suitable for dense mixed-signal boards. Surface-mount assembly; the enable pin allows external power sequencing or shutdown without a separate load switch. On-chip protection includes overcurrent limiting, thermal shutdown, and reverse-polarity protection — the regulator survives a miswired input or a sustained output short without external clamp diodes in most cases. ## Active lifecycle and compliance — sourcing posture ROHS3 compliant — no restricted substances above the threshold limits, which clears regulatory acceptance for EU, UKCA, and most global markets without an exemption review.","metaTitle":"TPS78833DBVT LDO Regulator, 3.3V Fixed Output, 150mA","metaDescription":"Texas Instruments TPS78833DBVT linear regulator: 3.3V fixed output, 150mA, 70dB PSRR at 1kHz, SOT-23-5.
