That 80 V ceiling covers 48 V telecom rails, 72 V industrial buses, and automotive load-dump transients without an external pre-regulator. ## Dropout, quiescent current, and protection — the real-world operating envelope Maximum dropout is 0.62 V at the full 250 mA load. That 620 mV headroom requirement sets the minimum input-to-output differential — if the input rail sags within 620 mV of the programmed output, the LDO falls out of regulation. The low Iq suits always-on or battery-backed rails where standby draw matters. On-chip protection includes overcurrent limiting, thermal shutdown, and reverse polarity protection — the reverse polarity block means the regulator survives a miswired input without an external series diode, which would otherwise add a dropout penalty. ## Output range and temperature grade The output is adjustable from a 1.24 V reference up to 60 V via an external resistor divider. The single regulator topology keeps the bill of materials simple — two feedback resistors and an output capacitor are the minimum external components. ## Package and thermal interface Housed in a 16-lead TSSOP with exposed pad (16-TSSOP-EP), the package footprint is 4.40 mm wide. Supplied in Tape & Reel (TR) or Cut Tape (CT) — the TR suffix indicates 2500-piece reel quantity for automated pick-and-place assembly.","metaTitle":"LT3012BEFE#TRPBF LDO, 250mA, 80V Input, 75dB PSRR","metaDescription":"Analog Devices LT3012BEFE#TRPBF adjustable LDO, 250mA output, 80V max input, 75dB PSRR at 120Hz.

That means mains-frequency ripple on the input is attenuated by a factor of about 5600 — critical when powering analog circuits from a switching supply that leaves 10-50 mV of 120 Hz ripple on the rail."},{"question":"Can the LT3012BEFE#TRPBF replace the ADP7182ACPZ-R7?","answer":"No — the ADP7182ACPZ-R7 is a negative-output LDO (adjustable down to -28 V input), while the LT3012BEFE#TRPBF is a positive-output regulator. They serve opposite polarity rails and are not pin-compatible or functional substitutes."},{"question":"What compliance documentation does Analog Devices provide for this part?","answer":"The LT3012BEFE#TRPBF is ROHS3 compliant.
