5 / 19 page AS1374 Datasheet - Electrical Character i s t ics www.austriamicrosystems.com/LDOs/AS1374 Revision 1.8 4 - 18 6 Electrical Characteristics VIN = VOUT + 0.5V, VOUT = 2.85V, CIN = COUT = 1µF, Typical values are at TAMB = +25ºC (unless otherwise specified). All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods. Table 3. Electrical Characteristics Symbol Parameter Condition Min Typ Max Unit TAMB Operating Temperature Range -40 +85 °C VIN Input Voltage Range 2 5.5 V VOUT Output Voltage Accuracy IOUT = 1mA, TAMB = +25ºC -1 +1 % IOUT = 100µA to 200mA, TAMB = +25ºC -1.5 +1.5 IOUT = 100µA to 200mA -2.5 +2.5 IOUT Maximum Output Current Each channel 200 mA IGND Ground Current One channel on, IOUT = 50µA 25 50 µA One channel on, IOUT = 200mA 30 55 µA ILIMIT Current Limit OUT = short 210 300 400 mA Dropout Voltage 1 1. Dropout is defined as VIN - VOUT when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V. 2V VOUT 2.5V, IOUT = 100mA 80 150 mV IQ Quiescent Current Both channels on, IOUT = 0.05mA 30 90 µA Both channels ON, VIN = VOUTNOM - 0.1V, IOUT = 0mA 50 VLNR Line Regulation VIN = (VOUT +0.5V) to 5.5V, IOUT = 1mA 0.02 %/V VLDR Load Regulation IOUT = 1 to 200mA 0.0005 %/mA ISHDN Shutdown Current OUT 1 and OUT 2 disable 0.01 2 µA PSRR Ripple Rejection f = 1kHz, IOUT = 10mA 85 dB f = 10kHz, IOUT = 10mA 65 f = 100kHz, IOUT = 10mA 50 Output Noise Voltage (RMS) f = 100Hz to 100kHz, ILOAD = 20mA 20 µV Enable Enable Input Bias Current 0.01 µA Enable Exit Delay 2 2.
