The MIC2937A/29371/29372 series are low-dropout voltage regulators designed for battery-powered equipment, cellular telephones, and automotive electronics. These regulators offer a combination of low quiescent current, low dropout voltage, and robust protection features, including reversed battery protection, fold-back current limiting, and automotive load dump protection. The MIC2937A provides fixed voltage outputs, while the MIC29371 and MIC29372 offer additional features like logic-compatible switching and adjustable output voltage.
