PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1) UNIT TJ = 25°C 1.1 over the junction IOUT = 100 mA V temperature range 1.3 –40°C to 125°C TJ = 25°C 1.15 over the junction VIN-V OUT Dropout Voltage (4) IOUT = 500 mA V temperature range 1.35 –40°C to 125°C TJ = 25°C 1.2 over the junction IOUT = 800 mA V temperature range 1.4 –40°C to 125°C ILIMIT Current Limit VIN – VOUT = 5 V, TJ = 25°C 800 1200 1500 mA TJ = 25°C 1.7 Minimum Load LM1117I-ADJ over the junction mA Current(5) VIN = 15 V temperature range 5 –40°C to 125°C TJ = 25°C 5 LM1117I-3.3 over the junction mA VIN ≤ 15 V temperature range 15 –40°C to 125°C Quiescent Current TJ = 25°C 5 LM1117I-5.0 over the junction mA VIN ≤ 15 V temperature range 15 –40°C to 125°C Thermal Regulation TA = 25°C, 30ms Pulse 0.01 0.1 %/W TJ = 25°C 75 fRIPPLE = 120 Hz, VIN – VOUT = 3 V over the junction Ripple Regulation dB VRIPPLE = 1 VPP temperature range 60 –40°C to 125°C TJ = 25°C 60 Adjust Pin Current μA over the junction temperature range –40°C to 125°C 120 TJ = 25°C 0.2 Adjust Pin Current 10 ≤ IOUT ≤ 800 mA, over the junction µA Change 1.4 V ≤ VIN – VOUT ≤ 10 V temperature range 10 –40°C to 125°C Temperature 0.5% Stability Long Term Stability TA = 125°C, 1000 Hrs 0.3% RMS Output Noise (% of VOUT), 10 Hz ≤ f ≤ 10 kHz 0.003% (4) The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input voltage. It is measured when the output voltage has dropped 100 mV from the nominal value obtained at VIN = VOUT + 1.5 V. (5) The minimum output current required to maintain regulation. 8 Submit Documentation Feedback Copyright © 2000–2016, Texas Instruments Incorporated Product Folder Links: LM1117 |
