Input voltage range extends to 15 V maximum, and the operating temperature span is 0°C to 125°C — this covers commercial and industrial ambient environments, though not the full automotive temperature band. ## Package and board-fit for SOT-223-4 Supplied in a SOT-223-4 surface-mount package (also referenced as TO-261-4, TO-261AA). The exposed pad on the bottom side provides the primary thermal path — the PCB copper area under the pad sets the junction-to-ambient resistance, so the layout should dedicate a flooded copper island with vias to an internal plane. The fixed-output configuration means no external resistor divider is needed for the output voltage; the 1.8 V is set internally. ## Protection features and compliance status On-chip protection includes over-current and over-temperature shutdown.","metaTitle":"Texas Instruments TLV1117-18CDCY LDO Regulator, 1.8V Fixed","metaDescription":"Active TLV1117-18CDCY from TI: 1.8V fixed-output LDO, 800mA, 75dB PSRR at 120Hz, SOT-223-4.

This means the regulator attenuates 120 Hz ripple — the fundamental frequency of full-wave-rectified mains — by a factor of about 5600, so a 100 mVpp input ripple appears as roughly 18 µVpp on the 1.8 V output. For a 16-bit ADC with a 1.8 V supply, that ripple stays well below 1 LSB."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV1117-18CDCY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV1117-18CDCY when reusing this data.
