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.
