MIC29302AWD-TR

MIC29302AWD-TR is a high-current, low-dropout voltage regulator that uses Microchip's proprietary Super βeta PNP process with a PNP pass element. The 3A LDO regulator features 560mV (full load) dropout voltage and very low ground current. Designed for high-current loads, this device also find applications in lower current, low-dropout critical systems, where their dropout voltages and ground current values are important attributes. Along with a total accuracy of ±2% (over temperature, line, and load regulation), the regulator features very fast transient recovery from input voltage surges and output load current changes. The application includes processor peripheral and I/O supplies, high-efficiency green computer systems, automotive electronics, high-efficiency linear lower supplies, battery-powered equipment, PC add-in cards, and high-efficiency post-regulator for switching supply.
