ELECTRICAL OPERATING CHARACTERISTICS (Note 3) (VIN = VOUT + 1.0 V, VEN = High, IOUT = 100 mA, CIN = COUT = 1 mF, ambient temperature of 25°C (over recommended operating conditions unless specified otherwise). Bold numbers apply for the entire junction temperature range.) Symbol Parameter Conditions Min Typ Max Unit VOUT−ACC Output Voltage Accuracy Initial accuracy for VOUT ≥ 2.0 V (Note 6) −1.0 +1.0 % −2.0 +2.0 TCOUT Output Voltage Temp. Coefficient 40 ppm/°C VR−LINE Line Regulation VIN = VOUT + 1.0 V to 5.5 V −0.2 ±0.1 +0.2 %/V −0.4 +0.4 VR−LOAD Load Regulation IOUT = 100 mA to 300 mA 0.7 1.2 % 1.5 VDROP Dropout Voltage (Note 4) IOUT = 300 mA 180 250 mV 300 IGND Ground Current IOUT = 0 mA 55 75 mA 90 IOUT = 300 mA 80 IGND−SD Shutdown Ground Current VEN < 0.4 V 1 mA 2 PSRR Power Supply Rejection Ratio f = 1 kHz, CBYP = 10 nF 64 dB f = 20 kHz, CBYP = 10 nF 54 ISC Output short circuit current limit VOUT = 0 V 180 mA TON Turn−On Time CBYP = 10 nF 150 ms eN Output Noise Voltage (Note 5) BW = 10 Hz to 100 kHz 45 mVrms ROUT−SH Shutdown Switch Resistance 250 W REN Enable pull−down resistor 2.5 MW VUVLO Under−voltage lock out (UVLO) threshold 2.1 V ESR COUT equivalent series resistance 5 500 mW ENABLE INPUT VHI Logic High Level VIN = 2.3 to 5.5 V 1.8 V VIN = 2.3 to 5.5 V, 0°C to +125°C junction temperature 1.6 VLO Logic Low Level VIN = 2.3 to 5.5 V 0.4 V IEN Enable Input Current VEN = 0.4 V 0.15 1 mA VEN = VIN 1.5 4 THERMAL PROTECTION TSD Thermal Shutdown 160 °C THYS Thermal Hysteresis 10 °C 3. Specification for 2.80 V output version unless specified otherwise. 4. Dropout voltage is defined as the input−to−output differential at which the output voltage drops 2% below its nominal value. During test, the input voltage stays always above the minimum 2.3 V. 5. Specification for 1.8 V output version. 6. For VOUT < 2.0 V, the initial accuracy is ±2% and across temperature ±3%. |
