Wide range output voltage line up (V OUT = 1.0 to 4.5 V)

L ow dropout voltage

V

DO = 175 mV (typ.) at 3.3 V output, I OUT = 300 mA

V

DO = 21 6 mV (typ.) at 2.5 V output, I OUT = 300 mA

V

DO = 2 9 7 mV (typ.) at 1.8 V output, I OUT = 300 mA

Low output noise voltage (V NO = 38 μ V rms t yp.) at 10Hz ≤ f ≤ 100kHz)

High ripple rejection ratio (72 dB (typ.) at 2.5 V output, IOUT = 10 mA, f = 1 kHz)

Fast load transient response (±80 mV (typ.) at 2.5 V output, IOUT = 1 mA ⇔ 300 mA)
