| ACE510 Technology Description Dual, 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 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 within2%. The ACE510 is available in SOT-23-6 package which is lead (Pb)- free Features * * * * * * * * * * * * * * * * * * Two low dropout voltage regulators 150mA output current for each LDO 25uA operating supply current per LDO Low 27uVRMS output noiseV~10V Standby Mode: 0.1uA Low 200mV dropout at 100mA load 65dB PSRR at kHz Excellent Line regulation: 0.05%/V Independent Shutdown controls 1.2V to 5.0V Factory-Preset Output Output Current Limit Highly Accurate: 2% (1% customized) Application Cellular phones Cordless phones and radio communication equipment Battery Powered equipment Notebook and hand-ole equipment Wireless LAN GPS receivers Typical Performance Characteristic: ACE505-1.8V Output Output Current Iout (mA) VER 1.2 1 ACE510 Technology Absolute Maximum Ratings Parameter Input voltage Power Dissipation SOT-23-6 Junction temperature Storage temperature Output Current TJ TS Symbol VIN Dual, Low noise, 150mA LDO regulator Max 10 200 125 - 45 to 150 200 Unit V mW C C mA O O Packaging Type SOT-23-6 6 5 4 1 2 3 Pin SOT-23-6(C) SOT-23-6(D) SOT-23-6(E) Function Vout1 1 6 6 Output 1 pin Vdd 2 2 5 Input pin Vout2 3 4 1 Output 2 pin CE2 4 3 3 Chip Enable pin2 GND 5 5 2 Ground pin CE1 6 1 4 Chip Enable pin1 VER 1.2 2 ACE510 Technology Ordering information Selection Guide ACE510 XX XX + H Halogen - free Pb - free CGM : SPT-23-6C DGM : SOT-23-6D EGM : SOT-23-6E Output Voltage Dual, Low noise, 150mA LDO regulator A:1.5V(Output1),2.5V(Output2) C:1.5V(Output1),3.0V(Output2) E:1.5V(Output1),4.0V(Output2) G:1.8V(Output1),2.5V(Output2) I: 1.8V(Output1),3.0V(Output2) K: 2.5V(Output1),1.8V(Output2) M:2.8V(Output1),1.8V(Output2) O:2.8V(Output1),2.8V(Output2) Q:3.0V(Output1),2.5V(Output2) S:3.0V(Output1),3.3V(Output2) U:3.3V(Output1),2.5V(Output2) W:5.0V(Output1),3.3V(Output2) Y:2.8V(Output1),3.3V(Output2) B:1.5V(Output1),2.8V(Output2) D:1.5V(Output1),3.3V(Output2) F:1.8V(Output1),1.8V(Output2) H:1.8V(Output1),2.8V(Output2) J:1.8V(Output1),3.3V(Output2) L:2.5V(Output1),2.5V(Output2) N:2.8V(Output1),2.5V(Output2) P:2.8V(Output1),3.0V(Output2) R:3.0V(Output1),3.0V(Output2) T:3.3V(Output1),1.8V(Output2) V:3.3V(Output1),2.8V(Output2) X:2.8V(Output1),1.5V(Output2) Z:3.3V(Output1),3.3V(Output2) VER 1.2 3 ACE510 Technology Block Diagram Dual, Low noise, 150mA LDO regulator Recommended Work Conditions Item Input Voltage Range Ambient Temperature Min Recommended Max Unit 8 V -40 85 Electrical Characteristics (Test Conditions: C1=1uF, C2=C3=2.2uF,TA=25, unless otherwise specified.)
