MIC29302AWD Datasheet PDF - Micrel

General Description

●The MIC29302A is a high-current, low-cost, low-dropout voltage regulator that uses Micrel"s proprietary Super βeta PNP® process with a PNP pass element. The 3A LDO regulator features 450mV (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.
