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 ORDERING INFORMATION - 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 Device IP1523 Package Operating Temp 14SOPH-8L -35OC ~ +85OC BLOCK DIAGRAM VIN 1 VOUT1 2 Vref PGND N/C 3 ON/OFF 4 VOUT2 5 N/C 6 N/C 7 June. 2003 (Rev.2) ON/OFF Control SW OCL SHUT DOWN OVP TSD PGND WWW.INTERPIONSEMI.COM -1- IP1523 DUAL OUTPUT VOLTAGE SERIES REGULATOR PIN CONNECTIONS PGND PGND IP1523 1 2 VIN VOUT1 3 4 5 N/C ON/OFF VOUT2 6 7 N/C N/C PIN DESCRIPTIONS NO SYMBOL I/O 1 VIN I 2 VOUT1 DESCRIPTION Input Supply Voltage Reg +3.3V Output O 3 N/C - No Connection 4 ON/OFF I ON/OFF Control 5 VOUT2 O Reg +2.0V Output 6 N/C - No Connection 7 N/C - No Connection 8 PGND - Power Ground June. 2003 (Rev.2) WWW.INTERPIONSEMI.COM -2- IP1523 DUAL OUTPUT VOLTAGE SERIES REGULATOR ABSOLUTE MAXIMUM RATINGS(TA=25OC) CHARACTERISTICS SYMBOL VALUE UNIT Maximum supply voltage Vinmax 10 V ON/OFF voltage Vonoff 10 V Power dissipation Pd 3.5* W Operating temperature Topr -35 ~ +85 O Storage temperature Tstr -55 ~ +150 O Maximum output current Iomax 700 C C mA Note> 1.
