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 £g F. Key features include current limit, thermal shutdown, fast .
