MIC29502WU

The MIC29502 is a high current, high accuracy and low-dropout voltage regulator. The 5A LDO regulator features 560 mV (full load) dropout voltage and very low ground current. Designed for high-current loads, these devices 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 MIC29502 has an adjustable output that can be set by two external resistors to a voltage between 1.24V and 15V. In addition, the device is fully protected against over current faults, reversed input polarity, reversed lead insertion, and over temperature operation. A TTL/CMOS logic enable (EN) pin is available in the MIC29502 to shutdown the regulator. When not used, the device can be set to continuous operation by connecting EN to the input (IN). The MIC29502 is available in TO263-5 package.
