Datasheet Summary
Adjustable 3-Channel Regulator General Description
The AAT2503 is a three-channel regulator consisting of a step-down converter with an input voltage range of 2.7V to 5.5V plus two low dropout (LDO) linear regulators. The step-down converter optimizes power efficiency throughout the load range. Pulling the MODE/ SYNC pin high enables "PWM Only" mode, maintaining constant frequency and low output ripple across the operating range. Alternatively, the converter may be synchronized to an external clock input to the MODE/SYNC pin. The step-down converter delivers up to 800mA of output current, while consuming 30µA of typical no load quiescent current. The switching frequency is 2MHz,...
