These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. ‡ Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals. electrical characteristics, TA = −25_C to 110_C, VC = VIN = 12 V, RFREQSET = 12 kW, CFREQSET = 330 pF, RSLOPE = 12 kW, CRAMP = 200 pF, CDELAYSET A−B = CDELAYSET C−D = 0.01 mF, IDELAYSET A−B = IDELAYSET C−D = −500 mA, and TA = TJ (unless otherwise stated) PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Undervoltage Lockout Start threshold 10.75 11.75 V UVLO hysteresis 0.5 1.25 2 V Supply Current Supply current, IIN startup VIN = 8 V, VC = 20 V, RSLOPE open, IDELAY = 0 150 600 µA Supply current, IC startup VIN = 8 V, VC = 20 V, RSLOPE open, IDELAY = 0 10 100 µA Supply current, IIN 30 44 mA Supply current, IC 15 30 mA Voltage Reference Output voltage TJ = 25_C 4.92 5 5.08 V Line regulation voltage VIN = 11 V to 20 V 1 10 mV Load regulation voltage IVREF = −10 mA 5 20 mV Total variation Line, Load, Temperature 4.9 5.1 V Noise voltage 10 Hz to 10 kHz 50 µVrms Long term stability 1000 hours, TJ = 125_C 2.5 mV Short circuit current VREF = 0 V, TJ = 25_C 60 mA Error Amplifier Offset voltage 5 15 mV Input bias current 0.6 3 µA Open loop voltage gain (AVOL) VE/AOUT = 1 V to 4 V 60 90 dB Common mode rejection ratio (CMRR) VCM = 1.5 V to 5.5 V 75 95 dB PSRR VIN = 11 V to 20 V 85 100 dB Output sink current VE/AOUT = 1 V 1 2.5 mA Output source current VE/AOUT = 4 V −1.3 −0.5 mA High-level output voltage (VOH) IE/AOUT = −0.5 mA 4 4.7 5 V Low-level output voltage (VOL) IE/AOUT = 1 mA 0 0.5 1 V Unity gain bandwidth 7 11 MHz Slew rate 6 11 V/ µsec |
