SD5400CY Parameter Table

Instructions for Using SD5400CY

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Use appropriate voltage regulation if the input voltage exceeds this range.

2. Output Current (Iout):

   • The maximum output current is 2.0A. Design your circuit to not exceed this limit to avoid damage.
   • For higher current applications, consider using external current boosters or parallel configurations.

3. Quiescent Current (Iq):

   • The quiescent current is typically 20μA, which is relatively low. This makes the SD5400CY suitable for battery-powered devices.

4. Dropout Voltage (Vdo):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation.
   • Ensure that the input voltage is at least 0.5V higher than the desired output voltage to maintain stable operation.

5. Load Regulation:

   • The load regulation is typically 0.05%, indicating that the output voltage will remain stable even with changes in load current.

6. Line Regulation:

   • The line regulation is typically 0.01%, meaning the output voltage will remain stable even with variations in input voltage.

7. Operating Temperature (Toper):

   • The device can operate in temperatures ranging from -40°C to 85°C. Ensure that the ambient temperature does not exceed these limits.

8. Storage Temperature (Tstg):

   • The device can be stored in temperatures ranging from -65°C to 150°C. However, avoid prolonged exposure to extreme temperatures.

9. Thermal Resistance (θja):

   • The thermal resistance is typically 50°C/W. Ensure adequate heat dissipation, especially when operating at high output currents.

10. PCB Layout Considerations:

    • Place the SD5400CY close to the power source and load to minimize trace resistance.
    • Use wide and short traces for power and ground connections to reduce inductance and resistance.
    • Place bypass capacitors (e.g., 10μF and 0.1μF) as close as possible to the Vcc and GND pins to filter out noise.

11. Capacitor Selection:

    • Use ceramic capacitors for bypassing due to their low ESR and high frequency performance.
    • For output filtering, use a combination of ceramic and electrolytic capacitors to handle both high-frequency and bulk capacitance requirements.

12. Safety Precautions:

    • Always use appropriate fuses and protection circuits to prevent overcurrent and overvoltage conditions.
    • Ensure proper grounding and isolation to avoid electrical hazards.

By following these parameters and instructions, you can ensure reliable and efficient operation of the SD5400CY in your application.
