Typical Characteristics (continued)
at T_J = 25°C, 1.4 V ≤ V_INx < 6.5 V, V_INx ≥ V_OUTx(TARGET) + 0.3 V, V_OUTx = 0.8 V, SS_CTRLx = GND, I_OUTx = 5 mA, V_ENx = 1.1 V,
C_OUTx = 10 μF, C_NR/SSx = 0 nF, C_FFx = 0 nF, PGx pin pulled up to V_OUTx with 100 kΩ, and SS_CTRLx = GND (unless otherwise
noted)
