LOW-INPUT VOLTAGE LDO ELECTRICAL CHARACTERISTICS (VINL3 = 3.6V, COUT10 = COUT11 = COUT12 = 2.2µF, TA = 25°C, unless otherwise specified.) : VNOM refers to the nominal output voltage level for VOUT as defined by the Ordering Information section. : IMAX Maximum Output Current. : Dropout Voltage is defined as the differential voltage between input and output when the output voltage drops 100mV below the regulation voltage (for 3.1V output voltage or higher). : LDO current limit is defined as the output current at which the output voltage drops to 95% of the respective regulation voltage. Under heavy overload conditions the output current limit folds back by 50% (typ) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Operating Voltage Range 1.7 5.5 V VOUT ≥ 1.0V, IOUT = 10mA -1 VNOM 1 % Output Voltage Accuracy VOUT < 1.0V, IOUT = 10mA -10 10 mV Line Regulation VINL = Max (VOUT + 0.5V, 3.6V) to 5.5V 0.5 mV Load Regulation IOUT = 1mA to IMAX 0.1 V/A Power Supply Rejection Ratio f = 1kHz, IOUT = 20mA, VOUT = 1.2V 50 dB f = 10kHz, IOUT = 20mA, VOUT = 1.2V 40 Supply Current per Output Regulator Enabled 22 µA Regulator Disabled 0 2 Soft-Start Period VOUT = 3.0V 100 µs Power Good Threshold VOUT Rising 92 % Power Good Hysteresis VOUT Falling 3.5 % Output Noise IOUT = 20mA, f = 10Hz to 100kHz, VOUT = 1.2V 30 µVRMS Discharge Resistance LDO Disabled, DIS[ ] = 1 1.5 kΩ LDO rated at 150mA (REG10) Dropout Voltage IOUT = 80mA, VOUT > 3.1V 100 200 mV Maximum Output Current 150 mA Current Limit VOUT = 95% of regulation voltage 180 mA Recommend Output Capacitor 2.2 µF LDO rated at 350mA (REG11 & REG12) Dropout Voltage IOUT = 160mA, VOUT > 3.1V 100 200 mV Maximum Output Current 350 mA Current Limit VOUT = 95% of regulation voltage 400 mA Recommend Output Capacitor 2.2 µF |
