Instructions for Using SCY4103:
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7V to 5.5V.
- Use appropriate decoupling capacitors (typically 1μF ceramic) close to the VIN pin to stabilize the input.
Output Voltage (VOUT):
- The output voltage is fixed at 3.3V.
- No external components are required to set the output voltage.
Output Current (IOUT):
- The device can provide up to 300mA of output current.
- For higher current applications, consider using a heat sink or a more powerful regulator.
Quiescent Current (IQ):
- The quiescent current is typically 1.5μA, making it suitable for low-power applications.
Dropout Voltage:
- The dropout voltage is typically 250mV at a load current of 300mA and an input voltage of 3.6V.
- Ensure the input voltage is at least 250mV higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is ±1% from 0mA to 300mA, ensuring stable output voltage over a wide range of load currents.
Line Regulation:
- The line regulation is ±1% from 2.7V to 5.5V, ensuring stable output voltage over the entire input voltage range.
Ripple Rejection:
- The ripple rejection is 70dB at 1kHz, effectively filtering out input voltage noise.
Operating Temperature:
- The device operates reliably from -40°C to 85°C.
- Avoid operating the device outside this temperature range to prevent damage or reduced performance.
Storage Temperature:
- Store the device between -65°C and 150°C to ensure long-term reliability.
PCB Layout:
- Place the SCY4103 as close as possible to the load to minimize trace resistance and inductance.
- Use wide, short traces for power and ground connections to reduce parasitic effects.
Capacitors:
- Use high-quality, low-ESR (Equivalent Series Resistance) capacitors for both input and output.
- A typical configuration includes a 1μF ceramic capacitor on the input and a 1μF ceramic capacitor on the output.
By following these guidelines, you can ensure optimal performance and reliability of the SCY4103 in your application.
