AAT2500M数据手册Skyworks中文资料规格书

描述 Description

The AAT2500M is a high efficiency 400mA step-down converter and 300mA low dropout (LDO) linear regulator for applications where power efficiency and solution size are critical. The typical input power source can be a single-cell Lithium-ion/polymer battery or a 5V or 3.3V power bus.
The step-down converter is capable of delivering up to 400mA output current, uses a typical switching frequency of 1.8MHz to greatly reduce the size of external components, offers high speed turn-on and maintains a low 25μA no load quiescent current.
The LDO is capable of delivering up to 300mA output current.
The AAT2500M is available in the Pb-free, space-saving 12-pin TSOPJW package and is rated over the -40°C to +85°C operating temperature range.
