That 1.8 V output is the fixed version — no external resistor divider needed — so it drops straight into a BOM line that calls for a regulated 1.8 V supply for a core, I/O bank, or analog front-end. The 65 dB PSRR at 120 Hz means this regulator rejects 120 Hz ripple from a full-wave rectified supply by a factor of roughly 1800 — critical when the input comes from a lightly filtered bulk rail feeding sensitive analog circuitry like an ADC reference or a VCO supply. At higher frequencies the rejection rolls off, so upstream filtering ahead of the LDO is still the right call for switching-noise rejection above a few kHz. Dropout is 0.45 V max at the full 500 mA load — the input rail needs to stay above 2.25 V to keep the output in regulation. ## Industrial temperature grade and protection — deployment context On-chip protection includes over-current, over-temperature, and reverse polarity — the reverse-polarity clamp means a swapped supply rail won't instantly kill the regulator, which is a real help during bench bring-up or field maintenance. The Enable pin (active high) lets a microcontroller or supervisor shut down the 1.8 V rail to save power — quiescent current in shutdown drops to near-zero, though the exact number isn't in this spec set. ## Active lifecycle and sourcing posture It is a current-production part, sourced through authorized and independent distribution channels. The Tape & Reel suffix (TR) means it ships on 13-inch reels for automated pick-and-place; Cut Tape (CT) is also available for prototype or low-volume builds. The 8-SO package is a standard JEDEC outline, so existing solder stencils and reflow profiles for SOIC-8 apply without adjustment.","metaTitle":"LT1763CS8-1.8#TRPBF LDO, 1.8V 500mA, 65dB PSRR","metaDescription":"Analog Devices LT1763CS8-1.8#TRPBF linear regulator, 1.8V fixed output, 500mA, 65dB PSRR at 120Hz, -40°C to 125°C, 8-SOIC.

That means it attenuates 120 Hz ripple from a rectified AC supply by a factor of about 1800 — important for keeping noise off sensitive analog rails like ADC references or PLL supplies."},{"question":"Will LT1763CS8-1.8#TRPBF drop into a board designed for ADP7105ACPZ-1.8-R7?","answer":"Both are 1.8 V fixed-output LDOs in a similar performance class with 500 mA output and 20 V max input, but the ADP7105 adds Power Good and Under Voltage Lockout features. The LT1763CS8-1.8#TRPBF is an 8-SOIC package; the ADP7105ACPZ-1.8-R7 is an LFCSP.
