OUTPUT NOISE OUTNOISE 10 Hz to 100 kHz, VOUT = 0.75 V 125 µV rms 10 Hz to 100 kHz, VOUT = 3.3 V 450 µV rms POWER SUPPLY REJECTION RATIO PSRR 1 kHz, VOUT = 0.75 V 70 dB 1 kHz, VOUT = 3.3 V 56 dB 1 Accuracy when OUT is connected directly to ADJ. When OUT voltage is set by external feedback resistors, absolute accuracy in adjust mode depends on the tolerances of resistors used. 2 Based on an end-point calculation using 10 mA and 1 A loads. See Figure 11 for typical load regulation performance for loads less than 10 mA. 3 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output voltages above 2.5 V. 4 Start-up time is defined as the time between the rising edge of EN to OUT being at 95% of its nominal value. 5 Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 1.0 V output voltage is defined as the current that causes the output voltage to drop to 90% of 1.0 V, or 0.9 V. Rev.
