2 / 6 page TS4274 5V/400mA Fixed Voltage Ultra Low Dropout Voltage Regulator 2/6 Version: B13 Electrical Characteristics ( VIN=VOUT+1V, IL=5mA, CO=10uF, TA=25 oC, unless otherwise noted) Parameter Conditions Min Typ Max Unit Output Voltage 5mA ≤ I L ≤ 500mA, Vo+1V ≤ V IN ≤ 26V 2.40 2.5 2.60 V 3.17 3.3 3.43 4.80 5.0 5.20 Input Supply Voltage -- -- 26 V Output Voltage Temperature Coefficient -- 50 150 ppm/ oC Line Regulation Vo+1V ≤ V IN ≤ 26V -- 0.05 0.5 % Load Regulation 5mA ≤ I L ≤ 400mA -- 0.2 2.0 % Dropout Voltage (Note 4) IL=100mA IL=250mA IL=400mA -- -- -- 100 300 500 200 400 600 mV Quiescent Current (Note 5) IL=100uA IL=250mA IL=400mA -- -- -- 200 10 25 300 15 35 uA mA mA Short Circuit Current (Note 6) VOUT=0 -- 600 900 mA Output Noise, 10Hz to 100KHz, IL=10mA CL=2.2uF CL=3.3uF CL=33uF -- -- -- 500 350 120 -- -- -- uVrms Power Supply Ripple Rejection F=100Hz, Vr=0.5Vss -- 60 -- dB Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed specifications and test conditions see the electrical characteristics. Note 2: Maximum positive supply voltage of 35V must be limited duration (<100mS) and duty cycle (<1%). Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ, the junction to ambient thermal resistance, θJA, and the ambient temperature, Ta. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The effective value of θJA can be reduced by using a heatsink. Note 3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 4: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current and output load current. Note 5: Output current will decrease with increasing temperature, but it will be not dropped below 400mA at the maximum specified temperature. |
