The maximum dropout voltage is 0.6V at the full 3A load, meaning the input rail needs at least 12.6V to maintain regulation — a tight headroom that keeps the pass element dissipation manageable in a TO-220-3 package. Operating temperature spans -40°C to 125°C, so this regulator fits industrial enclosures, outdoor telecom cabinets, and engine-bay electronics where the ambient can swing well beyond commercial limits. ## Protection features and thermal design margin On-chip protection covers over-current, over-temperature, reverse polarity, and transient voltage. The over-temperature shutdown gives the board a thermal budget safety net if the heatsinking is marginal — the TO-220 tab can be bolted to a chassis or a dedicated heatsink for high-current operation. Maximum input voltage is 26V, so the part can run from a 24V industrial bus with enough headroom for transients without needing a pre-regulator. ## Sourcing status and package format The part is sourced to order; no stock-holding claim is made here.","metaTitle":"MIC29300-12WT 12V Fixed 3A Linear Regulator TO-220-3","metaDescription":"Active production 12V fixed-output LDO, 3A continuous, 0.6V max dropout at full load.
