Instructions for Use:

1. Supply Voltage (Vcc):

   • Ensure the input voltage is within the range of 4.5V to 5.5V.
   • Avoid exceeding the maximum supply voltage to prevent damage.

2. Output Voltage (Vout):

   • The output voltage is fixed at 3.3V. No external resistors are required for adjustment.

3. Output Current (Iout):

   • The regulator can provide up to 200mA of current. Ensure the load does not exceed this limit to avoid overheating or damage.

4. Quiescent Current (Iq):

   • The quiescent current is typically 1mA. This is the current consumed by the regulator when no load is present.

5. Dropout Voltage (Vdo):

   • The dropout voltage is typically 1.2V. The input voltage must be at least 1.2V higher than the output voltage to ensure proper regulation.

6. Load Regulation:

   • The load regulation is 0.5 mV/mA, indicating that the output voltage will change by 0.5 mV for every 1 mA change in load current.

7. Line Regulation:

   • The line regulation is 0.5 mV/V, indicating that the output voltage will change by 0.5 mV for every 1 V change in input voltage.

8. Thermal Resistance (θJA):

   • The thermal resistance from junction to ambient is 65°C/W. Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.

9. Operating Temperature (Toper):

   • The device is designed to operate within the temperature range of -40°C to 85°C. Avoid operating outside this range to prevent performance degradation or damage.

10. Storage Temperature (Tstg):

    • The device can be stored between -65°C and 150°C. However, ensure it is brought to room temperature before use to avoid condensation and potential damage.

Layout Considerations:

• Place the input and output capacitors as close as possible to the regulator to minimize noise and improve stability.
• Use a 10μF tantalum capacitor on the input and a 10μF ceramic capacitor on the output for optimal performance.
• Ensure good PCB layout practices to minimize inductance and parasitic effects.

Handling Precautions:

• Handle the device with care to avoid static discharge, which can damage the internal components.
• Use appropriate ESD protection equipment when handling the device.
• Follow the recommended soldering profile to avoid thermal damage during assembly.
