Typical Performance Characteristics

Efficiency vs. Load Current: VIN = 3.3V, VOUT (from

top to bottom) = 2.5, 1.8, 1.2V

Efficiency vs. Load Current: VIN = 5.0V, VOUT (from

top to bottom) = 3.3, 2.5, 1.8, 1.2V

Output Ripple: VIN = 3.3V, VOUT = 1.0V, Iout = 400mA

CIN = 2.2μF/0603, COUT = 10μF/0603 + 2.2uF/0603

Output Ripple: VIN = 3.3V, VOUT = 1.0V, Iout = 400mA

CIN = 2.2μF/0603, COUT = 10μF/0603 + 2.2uF/0603

Output Ripple: VIN = 5V, VOUT = 1.0V, Iout = 400mA
