Ishort typical value of 120 mA for t= 400 µs during the power on 2. Vs_Low = 3.5 V@VO = 0.8 V, 1.2 V,1.5 V,1.8 V& 2.5 V; Vs_Low=5 V@ VO= 2.8 V & 3.3 V, Vs_Low= 6 V@VO = 5 V 3. Parameters are guaranteed by design 4. Referred to Figure 30. Maximum load variation response 5. Considering that the minimum operating input voltage is 2.15 V, the dropout voltage (Vdp) is not defined for output voltages below 1.8 V.
