ELECTRICAL SPECIFICATIONS
MIN and MAX limits are valid for the recommended ambient temperature range of -40°C to 85°C. Typical values represents
statistically the utmost probability at following conditions: VIN = 3.3V, VOUT = 1.8V, IOUT = 2A, CIN1 = 47µF ceramic, CIN2 =
220µF poly-tantalum, COUT1 = 47µ ceramic, COUT2 = 100µF poly-tantalum unless otherwise noted.
