SS8027GT32TB

SS8027G 3.3V 1A Low Dropout Regulator FEATURES Dropout voltage typically 0. 8V @ I O = 1A Output current in excess of 1A Output voltage accuracy ±2% Quiescent current, typically 600µA Internal short circuit current limit Internal over temperature protection DESCRIPTION The SS8027G positive 3.3V voltage regulator features the ability to source 1A of output current with a dropout voltage of typically 0.8V over the entire operating temperature range. A low quiescent current is provided over the entire output current range. The typical quiescent current is 0.6mA. Furthermore, quiescent current is reduced when the regulator is in the dropout mode (V IN < 3.3V). Familiar regulat or features such as over-temperature and over-current protection circuits are provided to prevent the device from being damaged by abnormal operating conditions. APPLICATIONS CD-R/W ADSL Cable Modem Set -Top-Box LAN switch/Hub Router DVD-R/W Pb-free, RoHS compliant.
