MIC2807-MMYML-TR

Overview

The MIC2807-MMYML-TR is a specialized power management IC designed for mobile phone applications. It integrates a high-performance DC/DC converter intended for powering power amplifiers (PA) with dual low-noise low dropout (LDO) regulators for the rest of the radio frequency section. The device operates within an input voltage range of 2.7 V to 5.5 V. It provides two output voltages, both specified at 2.85 V. The DC/DC converter supports an output current of 300 mA at 2.85 V, while the LDOs provide 30 mA each at 2.85 V. The component utilizes a Buck topology and is housed in a 17-MLF package.
