It accepts an input from 2.5V to 5.5V — covering single-cell Li-ion and standard 3.3V/5V logic rails — and produces a main output adjustable from 3V to 5.6V, a positive rail adjustable up to 20V, and a negative rail adjustable down to -18V, plus one additional regulated output. The fourth output is typically used for the gate-on voltage or a separate analog supply. This rail count and voltage range directly map to the bias sequence required by most TFT source drivers and gate drivers — the positive rail drives the source IC, the negative rail handles the gate-off level, and the main output powers the logic section. ## Industrial temperature qualification and compact footprint The 0.5 mm pitch QFN is manageable with standard SMT processes. ROHS3 compliant. No known obsolescence risk for the foreseeable future.","metaTitle":"TPS65123RGTT – Texas Instruments TFT LCD Bias Supply PMIC","metaDescription":"TPS65123RGTT from TI: 4-output converter for TFT LCD, input 2.5V–5.5V, adjustable ±18V rails, 16-VQFN (3x3mm).

The electrical characteristics are identical across all package variants of the TPS65123 family."},{"question":"Can TPS65123RGTT replace a single-output regulator in a TFT bias design?","answer":"No — this is a four-output converter, not a single LDO or switcher. It generates the positive source voltage, negative gate-off voltage, main logic rail, and a fourth output in one IC. Replacing it with a single-output part would require multiple separate regulators and lose the integrated sequencing and small footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65123RGTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65123RGTT when reusing this data.
