AAT2503 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.
