Typical performance characteristics

Figure 30. Load transient (VOUT = VADJ)

Figure 31. Startup transient

VOUT = VADJ, VIN = VEN = 3.5 V, IOUT = 1 mA to 200 mA,

COUT = 1 µF, tr = tf = 5 µs

VOUT = 3 V, VIN = VEN = 0 to 4.2 V, IOUT = 1 mA, CIN = COUT

= 1 µF, tr = tf = 5 µs

Figure 32. Enable transient (VOUT = VADJ)

Figure 33. Enable transient (VOUT = 3 V)

VOUT @ 0.8 V, VIN = 1.9, VEN = 0 to VIN, IOUT = 200 mA,

COUT = 1 µF, tr = tf = 1 µs

VIN = 4 V, VEN = 0 to VIN, IOUT = 200 mA, CIN = COUT = 1 µF,

tr = tf = 1 µs
