LTC3586-2/LTC3586-3
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T_A = 25°C. V_BUS = 5V, BAT = 3.8V, V_IN1 = V_IN2 = V_IN3 = V_IN4 = V_OUT3 = 3.8V,
V_OUT4 = 5V, R_PROG = 1k, R_CLPROG = 3.01k, unless otherwise noted.
