EUP7559

EUP7559 Low Noise Dual 300mA LDO with Independent Shutdown DESCRIPTION The EUP7559 is a dual low dropout linear regulator capable of sourcing 300mA current per regulator. The EUP7559 is stable with small ceramic output capacitors. The performance of EUP7559 is optimized for battery power systems to deliver low noise, low dropout voltage, low quiescent current and excellent line and load transient response. The EUP7559 is available in fixed output voltages in the 8-pin 3mm¡Ñ 3mm TDFN leadless package. www.DataSheet4U.com FEATURES z z z z z z z z z z z z z Input Voltage Range: 2.5V to 6V 300mA Output Current per LDO Low Dropout Voltage of 55mV@100mA Low Quiescent Current of 115µA per LDO High PSRR 70dB at 1kHz Low Output Noise Thermal Shutdown Protection Current Limit Protection Separate Enable pin per LDO Stable with Ceramic Output Capacitor 1.5V to 3.3V Pre-set Output 3mm¡Ñ 3mm TDFN-8 Package RoHS Compliant and 100% Lead (Pb)-Free APPLICATIONS z z z z Cellular Phones PDAs and Palmtop Computers Wireless LAN Cards Hand-Held Instruments Typical Application DS7559 Ver 1.0 May. 2007 1 EUP7559 Block Diagram www.DataSheet4U.com DS7559 Ver 1.0 May. 2007 2 EUP7559 Pin Configurations Package Type Pin Configurations TDFN-8 www.DataSheet4U.com Pin Description PIN INA ENA Pin 1 2 DESCRIPTION LDO A Regulator Input.
