For a 1 Vpp ripple on the input, the output sees roughly 0.56 mVpp at that frequency. ## Dropout voltage and load regulation At lighter loads the dropout is lower, but the 0.45 V ceiling is the number to budget for worst-case headroom. An Enable pin (active high) allows the regulator to be shut down for power sequencing or low-power standby. On-chip protection includes over-current limiting, thermal shutdown, and reverse-polarity protection — the latter is unusual for an LDO and prevents damage if the input is accidentally reversed. ## Package and sourcing fit A tube variant (LT1763CS8-3.3#PBF) is also available for prototyping or low-volume builds. Analog Devices lists the product status as Active — no end-of-life notice or last-time-buy window is in effect. The part is ROHS3 compliant.","metaTitle":"LT1763CS8-3.3#TRPBF LDO Regulator, 3.3V 500mA 8-SOIC","metaDescription":"Analog Devices LT1763CS8-3.3#TRPBF LDO, fixed 3.3V output, 500mA, 65dB PSRR at 120Hz, -40°C to 125°C, 8-SOIC.

This means the regulator attenuates 120 Hz ripple (the fundamental frequency from full-wave rectified mains) by a factor of roughly 1800:1, making it suitable for post-rectifier filtering in analog supply chains."},{"question":"Will LT1763CS8-3.3#TRPBF drop into a board designed for LT1763CS8-2.5#TRPBF?","answer":"The package and pinout are identical — both are 8-SOIC with the same Enable and protection features. The only difference is the fixed output voltage: 3.3 V vs 2.5 V. If the downstream circuitry is rated for 3.3 V, the swap is a direct drop-in. If the load expects 2.5 V, the 3.3 V output will overvoltage it, so the board must be re-verified for the higher rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1763CS8-3.3~4TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1763CS8-3.3~4TRPBF when reusing this data.
