Functional Description
The AAT2500M is a high performance power man-
agement IC comprised of a buck converter and a lin-
ear regulator. The buck converter is a high efficien-
cy converter capable of delivering up to 400mA.
Operating at 1.8MHz, the converter requires only
three external power components (C
IN
, C
OUT
, and
L
X
) and is stable with a ceramic output capacitor.
The linear regulator delivers 300mA and is also sta-
ble with ceramic capacitors.
Linear Regulator
The advanced circuit design of the linear regulator
has been specifically optimized for very fast start-
up and shutdown timing. This proprietary LDO has
also been tailored for superior transient response
characteristics. These traits are particularly impor-
tant for applications that require fast power supply
timing.
The high-speed turn-on capability is enabled
through implementation of a fast-start control cir-
