Dual Channel 1A Low Dropout Regulator
PRELIMINARY
Unless otherwise specified, the following specifications apply over the operating ambient temperature 0°C ≤ TA ≤ 125°C except where
otherwise noted and the following test conditions: VIN = 5V, IOUT = 10mA, C1 = 4.7µF (Tantalum), C2 = 4.7µF (Tantalum), and TJ = TA
25°C using low duty cycling methods.
