Its 28 µA quiescent current keeps the idle draw low, making it a fit for always-on subsystems in industrial sensors, automotive modules, or portable gear. The 60 dB PSRR at 1 kHz means it rejects supply ripple well enough to power a precision op-amp or an ADC reference without adding a second post-filter. ## Industrial temp and protection set Rated from -40°C to 125°C, this part handles engine-bay heat and cold-soak starts without derating the output. On-chip protection covers over-current, over-temperature, and reverse polarity — the reverse-polarity clamp is worth noting for field wiring where the input supply might be connected backwards during bench work. The enable pin lets a system supervisor gate the rail off in standby, dropping the load to near-zero draw. ## Package and footprint Housed in a SOT-23-5 (SOT-753), the part fits a compact PCB layout. The fixed output saves one feedback resistor compared to adjustable LDOs, which simplifies the BOM and shrinks the placement area. Surface-mount assembly is straightforward for reflow or wave-solder lines. ## Sourcing and lifecycle This part carries an Active lifecycle status with ROHS3 compliance. For a BOM that needs a 1.8V LDO in a SOT-23-5 footprint, the TPS76918DBVR is a current, manufacturable choice — no supply-risk flags.","metaTitle":"TPS76918DBVR Linear Regulator, 1.8V Fixed Output, 100mA","metaDescription":"TPS76918DBVR from TI: 1.8V fixed-output LDO, 100mA, 28µA quiescent current, 60dB PSRR at 1kHz.

For a different voltage, check the family's fixed-output variants."},{"question":"Is TPS76918DBVR compatible with a 3.3V input?","answer":"Yes. The maximum input voltage is 10V, so a 3.3V rail is well within range. The LDO will regulate to 1.8V with a dropout voltage that depends on load current — typical dropout at 100 mA is under 200 mV, so 3.3V in gives plenty of headroom."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS76918DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS76918DBVR when reusing this data.
