EUP7522-3.3DIR1

Preliminary EUP7522 Dual, 600mA LDO Regulator DESCRIPTION The EUP7522 is an efficient, precise dual-channel CMOS LDO regulator with very-low dropout voltage and low ground current. Both regulator outputs are capable of sourcing 600mA of output current. The EUP7522’s performance is optimized for CD/DVD -ROM, CD/RW or wireless communication supply applications, The EUP7522 regulators are stable with output capacitors as low as 2.2 μF. Key features include current limit, thermal shutdown, fast transient response, high output accuracy, and high ripple rejection ratio. The EUP7522 regulator is available in a fixed 3.3V/2.5V output voltage configuration. FEATURES Low Quiescent Current (Typically 130μA) Guaranteed 600mA Output Current Low Dropout Voltage:600mV at 600mA Wide Operating Voltage Ranges : 2.5V to 5.5V Ultra-Fast Transient Response Tight Load and Line Regulation Current Limiting Protection Thermal Shutdown Protection Only low-ESR Ceramic Capacitors Required for Stability Available in SOP-8 Package RoHS Compliant and 100% Lead (Pb)-Free APPLICATIONS CD/DVD-ROM, CD/RW Wireless LAN Card/Keyboard/Mouse Battery-Powered Equipment XDSL Router Typical Application Circuit Figure 1.
