General Description

The MIC29310 and MIC29312 are low cost versions of MIC29300 family low-dropout (LDO) regulators. Manufactured on Micrel’s proprietary Super beta PNP™ process, the MIC29310/2 is a 3A LDO regulator with very low-dropout voltage (600mV over the full load) and low ground current. Along with a total accuracy of ±2 (over temperature, line and load regulation) these regulators feature very fast transient recovery from input voltage surges and output load current changes.
