Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 1.5 V to 5.5 V.
   • The input voltage should be stable and clean to avoid affecting the output regulation.

2. Output Voltage (VOUT):

   • The TPS7A3001MDGNTEP provides fixed output voltages of 1.8 V, 2.5 V, or 3.3 V.
   • Select the appropriate output voltage based on your application requirements.

3. Dropout Voltage (VDROPOUT):

   • The dropout voltage is 140 mV at 100 mA load current.
   • Ensure that the input voltage is at least 140 mV higher than the desired output voltage to maintain regulation.

4. Quiescent Current (IQ):

   • The quiescent current is 16 μA under typical operating conditions.
   • This low quiescent current makes the device suitable for battery-powered applications.

5. Shutdown Current (ISD):

   • When the enable pin (EN) is set to 0 V, the shutdown current is 0.1 μA.
   • Use this feature to conserve power when the device is not in use.

6. Load Regulation:

   • The load regulation is 0.5% over a load range from 0 to 100 mA.
   • This ensures that the output voltage remains stable even with varying load currents.

7. Line Regulation:

   • The line regulation is 0.05% over the input voltage range from 1.5 V to 5.5 V.
   • This ensures that the output voltage remains stable even with variations in the input voltage.

8. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 70 dB at 100 Hz.
   • This high PSRR helps to filter out noise from the input supply, improving the quality of the output voltage.

9. Operating Temperature Range (TOPR):

   • The device can operate over a temperature range from -40°C to 125°C.
   • Ensure that the ambient temperature and thermal design allow the device to stay within this range.

10. Storage Temperature Range (TSTG):

    • The device can be stored at temperatures ranging from -65°C to 150°C.
    • Store the device in a dry environment to prevent damage from moisture.

Additional Notes:

• Capacitors:
  • Use ceramic capacitors with X7R dielectric for the input and output capacitors.
  • Typical values are 1 μF for both input and output capacitors.
• PCB Layout:
  • Place the input and output capacitors as close as possible to the device to minimize parasitic inductance.
  • Ensure good ground connections to reduce noise and improve stability.
• Enable Pin (EN):
  • The enable pin can be used to turn the device on and off.
  • A logic high on the EN pin enables the device, while a logic low disables it.
