Its 0.63V maximum dropout at the full 1A load means the input rail needs to stay at least that much above the set output voltage to keep regulation — a 3.3V output from a 5V rail gives 1.07V headroom, which is comfortable, but a 4.5V rail would be marginal at high current. Output is adjustable from a 1.24V reference up to the 16V input maximum, set by an external resistor divider. The enable pin lets a logic signal shut the regulator down, pulling the output to zero and dropping quiescent current to near zero. ## Protection set and temperature range On-chip protection covers overcurrent, overtemperature, and reverse polarity — the reverse polarity clamp means the regulator survives a reversed input without an external Schottky diode across the input, saving a component and a voltage drop. The 8-SOIC package (0.154\" wide, 3.90mm body) is a standard footprint that reflows on a standard SOIC-8 land pattern. The thermal pad is the die-attach paddle on the bottom — for 1A continuous at elevated ambient, the PCB copper area under the package becomes the primary heatsink; a 1-square-inch pour on the top layer keeps the junction below 125°C at 25°C ambient.","metaTitle":"MIC39102YM-TR Adjustable LDO, 1A, 8-SOIC, Active","metaDescription":"Microchip MIC39102YM-TR adjustable positive LDO regulator, 1A output, 0.63V dropout at 1A max, -40°C to 125°C, 8-SOIC.
