Note: Unless otherwise indicated, VIN1 = VIN2 = SHDN1,2 = 3.6V, COUT1 =CIN = 4.7 F, COUT2 =1 F, L =4.7 H,
VOUT1 (ADJ) = 1.8V, TA = +25°C. Boldface specifications apply over the TA range of -40°C to +85°C. TA = +25°C. Adjustable- or fixed-
output voltage options can be used to generate the Typical Performance Characteristics.
