If the voltage of the pin#4 rises above threshold voltage, then TR Q1 will be saturated and the main bias current will be shut down. on/off function August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM -6- IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR TYPICAL APPLICATION CIRCUIT PGND PGND IP1522 VIN 1 VOUT1 VOUT2 ON/OFF 2 3 4 N/C 5 N/C 6 N/C 7 10uF Vinput 3.3V 1.65V 10uF H L Von/off August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM -7- IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR INTERNAL CIRCUIT Pin no Pin name Internal circuit 2 Regulator output1 2 3 Regulator Output2 3 August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM -8- IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR INTERNAL CIRCUIT (Continued) Pin no Pin name Internal circuit 4 4 ON / OFF August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM -9- IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR ELECTRICAL CHARACTERISTICS CURVES VCC vs ICC 10 8 Icc (mA) 6 4 2 0 0 2 4 6 8 10 Vcc (V) VREF TEMPERTURE STABILITY 1.670 1.665 1.660 1.655 VREF (V) 1.650 1.645 1.640 1.635 1.630 -50 0 50 100 O 150 TEMP ( C) August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM - 10 - IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR ILoad1 vs Vdrop1 1.4 Dropout Voltage1 (V) 1.2 1.0 0.8 0.6 0 100 200 300 400 500 600 700 800 Output Current1 (mA) 2.2 ILoad2 vs Vdrop2 2.0 Dropout Voltage2 (V) 1.8 1.6 1.4 1.2 0 20 40 60 80 100 120 140 Output Current2 (mA) August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM - 11 - IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR ELECTRICAL CHARACTERISTICS CURVES (Continued) VOUT1 Load Regulation (Tj=25 C) 3.40 o 3.35 Output Voltage1 (V) 3.30 3.25 3.20 0 200 400 600 800 1000 1200 Output Current1 (mA) VOUT2 Load Regulation (Tj=25 C) 1.68 o 1.66 Output Voltage2 (V) 1.64 1.62 1.60 0 50 100 150 200 250 Output Current2 (mA) August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM - 12 - IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR ELECTRICAL CHARACTERISTICS CURVES (Continued) VOUT1 Load Transient Response 200 Output Voltage Deviation (mV) 100 Io=50mA Io=50mA 0 -100 Io=450mA -200 -300 0 20 40 60 80 100 Time (usec) VOUT2 Load Transient Response 200 Output Voltage Deviation (mV) 100 Io=10mA 0 Io=10mA Io=100mA -100 -200 -300 0 20 40 60 80 100 Time (usec) August. 2002 (Rev.6) WWW.INTERPIONSEMI.COM - 13 - IP1522 DUAL OUTPUT VOLTAGE SERIES REGULATOR PACKAGE DIMENSION 14SOPH-8L MIN0.05 (0.061 0.004) (0.019) 1.55 0.10 (MIN0.002) #1 4.216 0.47 0.406 1.80MAX (0.071MAX) +0.10 -0.05 8.70MAX (0.343MAX) 2.946 8.56 0.20 (0.347 0.008) 6.00 0.30 (0.236 0.012) (0.008,+0.004,-0.002) 3.95 0.2 (0.156 0.008) 0.20 +0.10 -0.05 5.72 0.60 0.20 (0.024 0.008) (0.225) 0~8 August. 2002 (Rev.6) 1.27TYP WWW.INTERPIONSEMI.COM (0.050TYP) - 14 - (0.008,+0.004,-0.002) |
