CXLD6475 dual, low-noise, low-dropout regulator delivers
at least 300mA of continuous output current. The output voltage
for each regulator is set independently by trimming. Output
voltages are selectable in 100mV steps within a range of 1.2V
to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at
100Hz. The CXLD6475 includes two independent logic-
controlled shutdown inputs and allows the output of each
regulator to be turned of independently.
CXLD6475 includes high accuracy voltage reference, error
amplifier, current limit circuit and output driver module CXLD6475
has excellent load and line transient response and good
temperature characteristics, which can assure the stability of chip
and power system. And it uses trimming technique to guarantee
output voltage accuracy within?%.
CXLD6475 is available in SOT-23-6 package which is lead(Pb)-free
