Its 65 dB PSRR at 120 Hz means ripple from a downstream switching converter or line-frequency rectifier is attenuated by a factor of roughly 1800 — critical for analog front-ends where supply noise couples into the signal path. Maximum dropout voltage is 0.45 V at 500 mA load. The input rail must stay at least 450 mV above 1.5 V across the full load range to maintain regulation; a 3.3 V bus with a 0.5 V drop in the feed path still leaves margin. Input voltage range extends to 20 V, so the part can be powered from a 12 V or 15 V intermediate bus without an additional pre-regulator. The Enable pin allows external sequencing or shutdown, and the integrated protection suite — over-current, over-temperature, and reverse polarity — covers the common fault modes in bench supplies and distributed power architectures. Housed in a 12-lead WFDFN with exposed pad (4 mm × 3 mm), the package requires a thermal land on the PCB to sink heat from the die. The Enable pin is active-high and can be tied to the input if sequencing is not required.","metaTitle":"LT1763IDE-1.5#PBF LDO Regulator, 500mA, 1.5V Fixed, 12-DFN","metaDescription":"Analog Devices LT1763IDE-1.5#PBF LDO, 500mA output, 1.5V fixed, 65dB PSRR at 120Hz, -40°C to 125°C, 12-DFN.

This means ripple from a 50/60 Hz rectifier or a downstream switching converter at 120 Hz is attenuated by a factor of approximately 1800, keeping the output clean enough for sensitive analog loads like ADC reference supplies or op-amp rails."},{"question":"Will LT1763IDE-1.5#PBF drop into a board designed for LT1763IDE-5#PBF?","answer":"The two parts share the same package (12-DFN), pinout, and control features, but the output voltage differs — 1.5 V fixed versus 5 V fixed. The PCB footprint and external components (input/output capacitors) are identical, but the output rail voltage changes, so the downstream load must be rated for 1.5 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1763IDE-1.5~4PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1763IDE-1.5~4PBF when reusing this data.
