6.5 Electrical Characteristics

Over full operating ambient temperature range. Typical values are at TA = 25°C. Unless otherwise noted, specifications apply

for condition VIN = EN = 3.6 V. External components CIN = 10 μF 0603, COUT = 10μF 0603, L = 1.0 μH (see the parameter

measurement information).
