The enable pin (Control Features: Enable) lets you shut down the regulator via a logic signal, dropping the quiescent current to near zero — useful for battery-powered equipment that sleeps between measurement cycles. ## Temperature grade and protection suite The wide range means the regulator maintains its 2.8 V output even when the PCB is hot from adjacent power components. On-chip protection includes over-current, over-temperature, and reverse polarity — the regulator survives a shorted output, a thermal runaway condition, or a miswired supply without failing catastrophically. Reverse polarity protection is uncommon in low-cost LDOs and adds robustness for field-installed equipment. ## Package and board-fit: SOT-23-5 The MIC5203-2.8BM5 TR comes in a SOT-23-5 package (also listed as SC-74A, SOT-753), a standard 5-pin surface-mount outline. The footprint matches the industry-wide SOT-23-5 land pattern, so no custom pad geometry is needed. The package is supplied in Bulk — not tape-and-reel — which is the exact ordering code a buyer must confirm for their pick-and-place feeder or hand-assembly process. Surface-mount mounting (Mounting Type: Surface Mount) means the part reflows with standard lead-free profiles. The small footprint saves board space in dense designs, but the 80 mA output limits the load to low-power rails — not for powering a motor driver or a high-current FPGA bank. For new designs, this part is a safe choice without obsolescence risk in the near term. Sourced through authorized distribution and independent channels. No stock-holding claim is made here — the part is quoted to order per RFQ.","metaTitle":"MIC5203-2.8BM5 TR Microchip LDO, 2.8V Fixed, 80mA, SOT-23-5","metaDescription":"MIC5203-2.8BM5 TR from Microchip Technology: 2.8V fixed-output LDO, 80mA, 0.6V dropout, -40°C to 125°C, SOT-23-5.
