The protection block includes over-current, over-temperature, and reverse polarity — three features that reduce external clamp diodes and supervisory circuitry on the board. Control features (Enable, Power Good, Reset) give the system designer sequenced-rail or fault-reporting hooks without extra glue logic. ## Package and ordering variant Supplied in an 8-SOIC (0.154\", 3.90 mm width) surface-mount package. The same die is available in other package variants; verify the exact ordering code for your assembly line. ## Lifecycle and sourcing posture TI lists the TPS77733DR as Active and ROHS3 compliant. No NRND or EOL notice is in effect, so it remains eligible for new-design qualification and production BOM commitment.","metaTitle":"TPS77733DR 3.3V 750mA LDO Regulator, 60dB PSRR, 8-SOIC","metaDescription":"TI TPS77733DR fixed 3.3V output LDO, 750mA, 60dB PSRR at 1kHz, 125µA Iq, -40°C to 125°C, 8-SOIC.

It remains suitable for new designs and production BOMs."},{"question":"What is the TPS77733DR's PSRR and why does it matter?","answer":"PSRR is 60 dB at 1 kHz. That means the regulator attenuates 1 kHz ripple on the input by a factor of 1000 — important when powering analog circuits like op-amps or ADCs that would otherwise couple supply noise into the signal path."},{"question":"Is the TPS77733DR compatible with the TPS77733?","answer":"The TPS77733DR is the Tape & Reel / Cut Tape ordering variant of the TPS77733 base device. The silicon and electrical specs are identical; only the shipping medium differs. If your BOM calls for the tube-shipped TPS77733, verify the DR suffix matches your assembly feeder requirements."},{"question":"What is the closest pin-compatible alternative to the TPS77733DR?","answer":"Within the same TI family, the TPS77701DR (adjustable output version) shares the same pinout and package, but requires external resistor dividers to set the output voltage. For a fixed-output drop-in, stick with the TPS77733DR or the TPS77718DR for a 1.8 V rail. No second-source manufacturer lists a direct pin-compatible alternate for this exact order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS77733DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS77733DR when reusing this data.
