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×3mm TDFN leadless package.
