For an analog front-end powered from a switching regulator, this PSRR figure attenuates the 120 Hz ripple by a factor of 4000, keeping the LDO's 2.5 V output clean enough for a 16-bit ADC reference or a precision op-amp rail without additional post-filtering. At 500 mA output with a fixed 2.5 V rail, this LDO is sized for powering the analog supply domain on a mixed-signal board — the 0.51 V max dropout at full load means the input rail needs to stay above 3.01 V to hold regulation at 500 mA. ## Wide input range and protection set Input voltage tolerance up to 45 V lets this part operate directly from a 24 V industrial bus or a 12 V automotive rail with margin for load-dump transients — no external pre-regulator needed. The quiescent current is 110 µA, which matters for always-on rails in battery-backed systems where the LDO's own draw competes with the load's sleep current. On-chip protection includes over-current limiting, thermal shutdown, and reverse-polarity protection — the reverse-polarity clamp means the part survives a miswired input without an external Schottky diode, saving board space and BOM cost on the input protection circuit. Control features — enable pin for sequencing, power-good flag for reset generation, and soft-start to limit inrush current into the output capacitor — are all integrated, so no external timing components are needed for a basic power-up sequence. ## Active lifecycle — no end-of-life pressure This part is suitable for new designs without a planned migration path.","metaTitle":"LT3065IMSE-2.5#PBF LDO, 500mA, 2.5V, 72dB PSRR","metaDescription":"Analog Devices LT3065IMSE-2.5#PBF LDO regulator, 500mA fixed 2.5V output, 72dB PSRR at 120Hz, 45V input, -40°C to 125°C.
