UTC U584/5/7 LINEAR INTEGRATED CIRCUIT 3~8 AMP 5V TO 3.3V VOLTAGE CONVERSION REGULATOR DESCRIPTION The UTC U584/585/587 voltage regulators are monolithic integrated circuits, designed for use in applications requiring a well regulated positive output voltage with +5V input. The output voltage can be adjustable from 3.8 V down to 1.3V. 1 TO-220 FEATURES *Low dropout performance. *Adjustable output down to 1.3V. *Line regulation typically below 0.1%. *Load regulation typically below 0.1%. *Output current can be up to 8 A for UTC U584. 1 TO-263 1: COMMON 2: OUTPUT 3: INPUT BLOCK DIAGRAM INPUT SAFE AREA PROTECTION CURRENT LIMITING OUTPUT OVER TEMPERATURE PROTECTION VOLTAGE REGULATION AMPLIFIER ADJUST UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R102-003,A UTC U584/5/7 PARAMETER Input Voltage Power Dissipation Operating Junction Temperature Range Storage Temperature Lead Temperature ( Soldering 10 Sec. ) LINEAR INTEGRATED CIRCUIT SYMBOL VIN PD TJ TSTG TLEAD ABSOLUTE MAXIMUM RATINGS VALUE 7 Internally Limited 0 to 125 -65 to 150 300 UNIT V W C C C ELECTRICAL CHARACTERISTICS PARAMETER Reference Voltage SYMBOL U584 U585 U587 TEST CONDITIONS 1.3V<=(VIN-VOUT)<=3V, 10mA<=IOUT<=8A 1.3V<=(VIN-VOUT)<=3V, 10mA<=IOUT<=5A , 1.3V<=(VIN-VOUT)<=3V, 10mA<=IOUT<=3A 2.75V<=VIN<=7V,IOUT= IFULLLOAD MIN * 1.225 (-2%) TYP MAX 1.25 1.275 (+2%) UNIT V Line Regulation (Note 1.2) Load Regulation (Note 1, 2, 3) Dropout Voltage U584/5/7 U584/5/7 U584/5/7 0.1 VIN-VOUT=1.3V.Tj=25C, 10mA<=IOUT<=IFULLLOAD | VREF=1%,IOUT= IFULLLOAD Tj>=25C Tj<=25C VIN-VOUT =1.3 V VIN-VOUT =1.3 V VIN-VOUT =1.3 V 1.5V<=(VIN-VOUT) <=3 V, 10mA<=IOUT<=IFULLLOAD 1.5V<=(VIN-VOUT) <=3V, VIN<=5V f=120Hz,COUT=25ATant, VIN-VOUT =1.3 V , IOUT= IFULLLOAD TA=25C,1000Hrs TA=125C,10Hz<=f<=10kHz * 0.2 1.2 1.2 * * 8.0 5.0 3.0 8.5 5.5 3.6 55 0.2 2 8 60 72 0.5 0.03 0.03 0.2 1.0 1.3 1.35 % % V V A A A A mA mA mA dB % % % C /W C /W U584 Current Limit (Note 3) U585 U587 Adjust Pin Current U584/5/7 Adjust Pin Current U584/5/7 Change (Note 3) Minimum Load U584/5/7 Current Quiescent Circuit U584/5/7 Current Ripple Rejection U584/5/7 Temperature Stability Long-Term Stability RMS Output Noise ( % of VOUT ) Thermal Resistance U584 Junction to Case U585/7 120 5 10 13 * * 1.0 1.6 3.0 The * denotes specifications which apply over the specified operating temperature range. Note 1: Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. UTC UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R102-003,A UTC U584/5/7 LINEAR INTEGRATED CIRCUIT Note 2: Line and load regulation are guaranteed up to the maximum power dissipation(15W for the UTC U584, 10W for the UTC U585). Power dissipation is determined by input / output differential and the output current. Guaranteed maximum output power will not be available over the full input-output voltage range. Note 3: IFULLLOAD is defined as the maximum value of output load current as a function of input-to-output voltage. Output current can be different for different input-to-output voltage.
