EUP7211

Preliminary EUP7211 Dual 150/300mA LDO DESCRIPTION The EUP7211 is a dual low dropout linear regulator. The first regulator is capable of sourcing 150mA, while the second regulator can source up to 300mA. The EUP7211 is stable with small ceramic output capacitors. The performance of EUP7211 is optimized for battery power systems to deliver low noise, low dropout voltage, low quiescent current and excellent line and load transient response. The EUP7211 is available in fixed output voltages in the 8-pin 3mm¡Ñ 3mm QFN leadless package. www.DataSheet4U.com FEATURES z z z Input Voltage Range: 2.5V to 5.5V Stable with Ceramic Output Capacitor 2 LDO Outputs: „ Output 1-150mA Output Current „ Output 2-300mA Output Current Low Dropout Voltage of 100mV@150mA Low Quiescent Current of 150µA High PSRR 70dB at 1kHz: Thermal Shutdown Protection Current Limit Protection 3mm¡Ñ 3mm QFN-8 Package RoHS Compliant and 100% Lead (Pb)-Free z z z z z z z APPLICATIONS z z z Cellular Phones Wireless Modems PDAs Typical Application DS7211 Ver0.2 Apr. 2005 1 Preliminary Block Diagram EUP7211 www.DataSheet4U.com Pin Configurations Part Number Pin Configurations EUP7211 QFN-8 Pin Description PIN VIN EN1 EN2 BYPASS NC GND VOUT2 VOUT1 Pin 1 2 3 4 6 5 7 8 Input voltage of the LDO Enable input to regulator 1 Enable input logic, enable high Optional bypass capacitor for noise reduction No connection Ground Output of regulator 2: 300mA output current Output of regulator 1: 150mA output current DESC...
