4 / 11 page ACE509 Technology Low noise, fast response 500mA LDO regulator VER 1.2 4 PSRR Ripple Rejection F=100Hz, Ripple=0.5Vp-p Vin=Set Vout+1V 65 dB Ilim Short Current Limit Vout=0V 200 mA Rpd CE Pull down Resistance 2.0 5.0 10.0 M Ω Vceh CE Input Voltage “H” 1.5 Vin V Vcel CE Input Voltage “L” 0 0.25 V en Output Noise BW=10Hz~100kHz 47 uVrms Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA or Iout=500mA. Vin1 is the input voltage at which the output voltage becomes 98% of Vout1 after gradually decreasing the input voltage. Typical Application Circuit CE In ACE509 VDD VOUT Out + Cap GND + Cap Application hints: Note1:Input capacitor (Cin=1uF) is recommended in all application circuit. Note2:Output capacitor (Cout=3.3uF/4.7uF) is recommended in all application to assure the stability of circuit. Explanation: ACE509 series is a group of positive voltage output, low noise, low power consumption, low dropout voltage regulator. ACE509 can provide output value in the range of 1.2V~4.5V every 0.1V step. It also can be customized on command. ACE509 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. ACE509 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%. |
