It takes an input up to 25 V and delivers a clean 12 V rail for loads that need the ripple knocked down — think analog supplies, sensor bias, or post-switcher clean-up on a 24 V bus. With 55 dB of PSRR at 120 Hz, it knocks down the 100/120 Hz ripple from a rectified mains supply by a factor of about 560 — so a 1 Vpp ripple on the input becomes under 2 mVpp on the output. That matters when the 12 V rail feeds an op-amp front-end or an ADC reference buffer. ## Why the TO-220-5 Full Pack matters for a field swap The TO-220-5 Full Pack (TO-220FP-5) is a fully isolated tab package — the metal back is not electrically connected to the die. That means you can bolt it to a chassis or heatsink without an insulating pad, which saves a part and a step on the line. It also makes the swap easier on site: no mica washer to lose, no thermal grease mess. Through-hole mounting with five pins — the pinout is standard for this family: input, ground, output, plus an enable pin and a no-connect. The enable pin lets you shut the output off without dropping the input rail, useful for sequencing or power-save modes. ## Protection set and temperature range On-chip protection covers over-current, over-temperature, and over-voltage — the regulator folds back or shuts down before the load or the regulator itself lets the smoke out. Over-voltage protection clamps the output if the input spikes above the rated max, which is a nice extra on a 24 V industrial rail that sees transients. The quiescent current is 2.5 mA typical, with a max supply current of 5 mA — not a micropower part, but fine for always-on rails where the load is in the hundreds of milliamps.","metaTitle":"ROHM BAJ2CC0WT LDO Regulator, 12V Fixed, 1A, TO-220-5","metaDescription":"ROHM BAJ2CC0WT linear regulator, 12V fixed output, 1A, TO-220-5 Full Pack.
