PARAMETER TEST CONDITIONS MIN(2) TYP(3) MAX(2) UNIT VIN Input voltage For operating temperature extremes: 2.5 6 V −40°C to 85°C 100 μA ≤ IOUT ≤ 300 mA VIN = VOUT + 0.5 V (1) −2 2 % of VOUT SET = OUT for the ADJ Versions ΔVOUT Output voltage tolerance (NOM) For operating temperature extremes: −3 3 −40°C to 85°C Output adjust range ADJ version only; VOUT for operating temperature extremes: 1.25 6 V −40°C to 85°C Maximum output current Average DC current rating; IOUT For operating temperature extremes: 300 mA −40°C and 85°C Output current limit 770 ILIMIT mA For operating temperature extremes: 330 −40°C to 85°C IOUT = 0 mA 90 IOUT = 0 mA; Supply current for operating temperature extremes: 270 μA IQ −40°C to 85°C IOUT = 300 mA 225 Shutdown supply current VO = 0 V, SHDN = GND 0.001 1 μA IOUT = 1 mA 0.4 IOUT = 200 mA 80 IOUT = 200 mA; VDO Dropout voltage(1)(4) mV for operating temperature extremes: 220 −40°C to 85°C IOUT = 300 mA 120 IOUT = 1 mA, 0.01 (VOUT + 0.5 V) ≤ VI ≤ 6 V (1) IOUT = 1 mA, (VOUT + 0.5 V) ≤ VI ≤ 6 Line regulation %/V ΔVOUT V(1); −0.1 0.1 for operating temperature extremes: −40°C to 85°C Load regulation 100 μA ≤ IOUT ≤ 300 mA 0.002 %/mA Output voltage noise IOUT = 10 mA, 10 Hz ≤ f ≤ 100 kHz 37 μVRMS en Output voltage noise density 10 Hz ≤ f ≤ 100 kHz, COUT = 10 μF 190 nV/ √Hz VIH, (VOUT + 0.5 V) ≤ VIN ≤ 6 V (1); for operating temperature extremes: 2 −40°C to 85°C VSHDN SHDN input threshold V VIL, (VOUT + 0.5 V) ≤ VIN ≤ 6 V (1); for operating temperature 0.4 extremes: −40°C to 85°C ISHDN SHDN input bias current SHDN = GND or IN 0.1 100 nA ISET SET input leakage SET = 1.3 V, ADJ version only(5) 0.1 2.5 nA (1) Condition does not apply to input voltages below 2.5 V because this is the minimum input operating voltage. (2) All limits are verified by testing or statistical analysis. (3) Typical values represent the most likely parametric norm. (4) Dropout voltage is measured by reducing VIN until VOUT drops 100 mV from its nominal value at VIN – VOUT = 0.5 V. Dropout voltage does not apply to the 1.8-V version. (5) The SET pin is not externally connected for the fixed versions. Copyright © 2002–2015, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LP3982 |
