Instructions for Using ACT74

  1. Power Supply Connection:

    • Connect the input voltage (VIN) to the VIN pin.
    • Ensure the input voltage is within the specified range (2.5V to 5.5V).
  2. Output Connection:

    • Connect the output voltage (VOUT) to the VOUT pin.
    • The output voltage is fixed at 3.3V.
  3. Ground Connection:

    • Connect the ground (GND) to both the VIN and VOUT pins to ensure proper operation.
  4. Capacitors:

    • Place a 1μF ceramic capacitor close to the VIN pin to filter out noise and stabilize the input voltage.
    • Place a 1μF ceramic capacitor close to the VOUT pin to stabilize the output voltage and improve transient response.
  5. Thermal Considerations:

    • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
    • Use a heatsink if necessary to keep the device within the operating temperature range.
  6. Load Regulation:

    • The output voltage may vary slightly with changes in load. The typical load regulation is 1%.
  7. Line Regulation:

    • The output voltage may vary slightly with changes in input voltage. The typical line regulation is 0.1% per volt.
  8. Power Supply Rejection Ratio (PSRR):

    • The device has a good ability to reject ripple from the input voltage, with a typical PSRR of 60 dB at 1 kHz.
  9. Operating Temperature:

    • The device is designed to operate within the temperature range of -40°C to 85°C.
  10. Storage Temperature:

    • Store the device in a dry environment within the temperature range of -65°C to 150°C.
  11. Handling Precautions:

    • Handle the device with care to avoid static damage.
    • Follow standard ESD (Electrostatic Discharge) precautions when handling the device.

By following these instructions, you can ensure optimal performance and reliability of the ACT74 regulator.
