| IP1523 DUAL OUTPUT VOLTAGE SERIES REGULATOR DESCRIPTION The IP1523 is a dual output voltage series regulator with output on/off control function. The nominal output voltages are 3.3V and 2.0V,respectively. The 3.3V regulator can provide the output current up to 550mA. While the 2.0V regulator can provide up to 500mA. When the IP1523 becomes off, all the output voltages are shut down. 14SOPH-8L FEATURES - 1-Fixed 3.3V Regulator with Internal NPN TR. - 1-Fixed 2.0V Regulator with Internal NPN TR. - Built-in TSD circuit. - Built-in Current Limit Circuit. - Built-in ON/OFF Control Circuit. - Built-in Over Voltage Protection Circuit. - Outputs Trimmed to +/-3% Tolerance ORDERING INFORMATION Device IP1523 Package 14SOPH-8L Operating Temp -35OC ~ +85OC BLOCK DIAGRAM VIN 1 VOUT1 2 Vref PGND N/C 3 ON/OFF 4 ON/OFF Control SW SHUT DOWN VOUT2 5 OCL OVP TSD N/C 6 PGND N/C 7 June. 2003 (Rev.2) WWW.INTERPIONSEMI.COM -1- IP1523 DUAL OUTPUT VOLTAGE SERIES REGULATOR PIN CONNECTIONS PGND PGND IP1523 1 2 3 4 5 6 7 VIN VOUT1 N/C ON/OFF VOUT2 N/C N/C PIN DESCRIPTIONS NO 1 2 SYMBOL VIN VOUT1 O 3 4 5 6 7 8 N/C ON/OFF VOUT2 N/C N/C PGND I O No Connection ON/OFF Control Reg +2.0V Output No Connection No Connection Power Ground I/O I DESCRIPTION Input Supply Voltage Reg +3.3V Output June. 2003 (Rev.2) WWW.INTERPIONSEMI.COM -2- IP1523 DUAL OUTPUT VOLTAGE SERIES REGULATOR ABSOLUTE MAXIMUM RATINGS(TA=25OC) CHARACTERISTICS Maximum supply voltage ON/OFF voltage Power dissipation Operating temperature Storage temperature Maximum output current SYMBOL Vinmax Vonoff Pd Topr Tstr Iomax VALUE 10 10 3.5* -35 ~ +85 -55 ~ +150 700 UNIT V V W O C O C mA Note> 1.
