3 / 8 page ACE1117 Technology 1A Positive Voltage Regulators VER 1.3 3 Note1: Low duty cycle pulse testing with which TJ remains unchanged. 2: The IQ of ACE1117-1.5 is 1.2mA (Typ.) 3: The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input Typical Application Adjustable Voltage Regulator Vin>=3.0V ACE1117 Vout=1.5V Vin Vout ADJ R1 Cin 124ohm Cout 10uF 22uF R2 24.9ohm VOUT=VREF * (1+R2/R1)+IADJ * R2 ACE1117-3.3 Fixed Voltage Regulator Application Hints The typical Linear regulator would require external capacitors to ensure stability. However, ACE1117 is designed in such a way that these external capacitor can be omitted if the PCB layout is tight and system noise is not very high. For better transient and PSRR performance, the Input and Output capacitors are still recommended. Input Capacitor An input capacitor of 10μF is recommended. Ceramic or Tantalum can be used. The value can be increased without upper limit. |
