Technology ACE510 Dual, Low noise, 150mA LDO regulator Description 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 27uVrms,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%.
