Instructions for Using ACT74
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).
Output Connection:
- Connect the output voltage (VOUT) to the VOUT pin.
- The output voltage is fixed at 3.3V.
Ground Connection:
- Connect the ground (GND) to both the VIN and VOUT pins to ensure proper operation.
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.
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.
Load Regulation:
- The output voltage may vary slightly with changes in load. The typical load regulation is 1%.
Line Regulation:
- The output voltage may vary slightly with changes in input voltage. The typical line regulation is 0.1% per volt.
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.
Operating Temperature:
- The device is designed to operate within the temperature range of -40°C to 85°C.
Storage Temperature:
- Store the device in a dry environment within the temperature range of -65°C to 150°C.
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.
