Instructions for Use

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.85V to 6.5V.
   • The input voltage should be stable and free from excessive ripple and noise.

2. Output Voltage (VOUT):

   • Set the output voltage using external resistors if the device is adjustable.
   • For fixed output versions, ensure the selected part matches the required output voltage.

3. Quiescent Current (IQ):

   • The quiescent current is typically 1.5 μA at 3.3V input and output. This low current consumption makes the device suitable for battery-powered applications.

4. Dropout Voltage (VDROPOUT):

   • The dropout voltage is 0.2V at 100 μA load current. Ensure the input voltage is at least 0.2V higher than the desired output voltage to maintain regulation.

5. Load Regulation:

   • The load regulation is 0.1% from 100 μA to 150 mA. This indicates that the output voltage remains stable over a wide range of load currents.

6. Line Regulation:

   • The line regulation is 0.1% from 2.85V to 6.5V input voltage. This ensures that the output voltage remains stable even with variations in the input voltage.

7. Output Current (IOUT):

   • The maximum continuous output current is 150 mA. Do not exceed this limit to avoid overheating or damage to the device.

8. PSRR (Power Supply Rejection Ratio):

   • The PSRR is 70 dB at 100 Hz, indicating good rejection of input voltage variations and noise.

9. Operating Temperature Range (TOPR):

   • The device operates reliably from -40°C to 125°C. Ensure the ambient temperature does not exceed these limits.

10. Storage Temperature Range (TSTG):

    • Store the device in an environment where the temperature ranges from -65°C to 150°C.

11. Capacitors:

    • Use appropriate input and output capacitors to stabilize the circuit and filter out noise. Typical values are 1 μF for both input and output capacitors.

12. PCB Layout:

    • Place the device close to the load to minimize trace inductance and resistance. Use wide and short traces for power and ground connections to reduce voltage drops and improve performance.

13. Thermal Management:

    • If operating at high output currents or in high ambient temperatures, consider adding a heatsink or ensuring adequate airflow to dissipate heat effectively.

14. Handling:

    • Handle the device with care to avoid static discharge and physical damage. Use proper ESD protection measures during handling and assembly.
