It takes an unregulated input up to 20 V and delivers an adjustable output from 1.2 V to 19.5 V set by two external resistors. The 75 dB PSRR at 120 Hz makes it a clean choice for post-switcher rails feeding sensitive analog loads — ADC front-ends, audio codecs, or precision references. The -40°C to 125°C operating range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules without a temperature derating curve to track. ## Package and mounting Maximum dropout is 0.49 V at the full 1.1 A load. ## Through-hole TO-220-5 — rework and thermal handling The TO-220-5 package is a through-hole part with a metal tab. That tab can be soldered to a PCB copper pour or bolted to a chassis heatsink for dissipating several watts. Through-hole leads survive multiple rework cycles — lift the part, not the pad — and the five-pin layout is wide enough to probe with a scope clip without shorting adjacent pins. ## Lifecycle and sourcing The LT1965IT#PBF shows an active lifecycle status — no last-time-buy notice, no NRND flag. It is ROHS3 compliant (lead-free). If you are cross-referencing against an older LT1965IT (non-#PBF suffix), the #PBF variant is the lead-free, ROHS3-compliant version — electrically identical, same package, same temp range.","metaTitle":"LT1965IT#PBF LDO Regulator, 1.1A, Adjustable, TO-220-5","metaDescription":"LT1965IT#PBF positive adjustable LDO, 1.1A output, 75dB PSRR at 120Hz, -40°C to 125°C, TO-220-5.
