MAX8890EGCAKM

Power Management - Specialized Overview

The MAX8890EGCAKM is an integrated cellular RF-section power-management IC manufactured by Maxim Integrated, now part of Analog Devices Inc. It provides fixed positive multiple output LDO regulation with three outputs: 3.3V, 2.5V, and a second 2.5V rail. The device operates within a supply voltage range of 2.5V to 5.5V and draws a typical supply current of 180µA. Designed for handheld and mobile devices, it functions reliably across an operating temperature range of -40°C to +85°C. The component is housed in a 12-TQFN (4x4) package with an exposed pad, suitable for surface-mount installation.
