Instructions for Using F5038H

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 4.5V to 5.5V.
   • Use a stable power source to avoid fluctuations that could affect performance.

2. Operating Temperature:

   • The device is designed to operate between -40°C and 85°C.
   • Avoid exposing the device to temperatures outside this range to prevent damage.

3. Output Current (Iout):

   • The maximum output current is 200mA.
   • For optimal performance, keep the load current below 100mA.

4. Input Voltage Range (Vin):

   • The input voltage should be within the range of 2.7V to 5.5V.
   • Ensure the input voltage is always higher than the output voltage by at least the dropout voltage.

5. Quiescent Current (Iq):

   • The quiescent current is very low, typically around 1μA.
   • This makes the F5038H suitable for battery-powered applications.

6. Dropout Voltage (Vdo):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation.
   • It typically ranges from 0.2V to 0.6V.

7. Load Regulation (ΔVout):

   • The change in output voltage due to changes in load current is minimal, typically less than 0.5%.

8. Line Regulation (ΔVout):

   • The change in output voltage due to changes in input voltage is minimal, typically less than 0.5%.

9. Ripple Rejection (RR):

   • The device can effectively reduce input voltage ripple, with a typical rejection of 70dB.

Additional Notes:

• Capacitors:

  • Use appropriate input and output capacitors to stabilize the voltage and reduce noise.
  • Recommended values are typically 1μF ceramic capacitors for both input and output.

• PCB Layout:

  • Ensure proper PCB layout to minimize noise and parasitic effects.
  • Keep traces short and direct, especially for power and ground connections.

• Storage:

  • Store the device in a dry, cool place to prevent moisture damage.
  • Handle with care to avoid static discharge, which can damage the device.
