ACE510
Technology
Description
D
ual, Low noise, 150mA LDO regulator
The ACE510 dual, low-noise, low-dropout regulator delivers at least 150mA of continuous output current.
The output voltage for each regulator is set independently by trimming. Voltages are selectable in 100mV
steps within a range of 1.2V to 5.0V.Typical output noise is 27uV
rms
,and PSRR is 65dB at 1KHz. The
ACE510 includes two independent logic-controlled shutdown inputs and allows the output of each
regulator to be turned of independenly.
The ACE510 includes high accuracy voltage reference, error amplifier, current limit circuit and output
driver module.
The ACE510 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±2%. The ACE510 is available in SOT-23-6 package which is lead (Pb)- free
