Instructions for Using BA10393N

1. Input Voltage:

   • Ensure the input voltage is within the specified range (2.7 V to 5.5 V) to avoid damage or improper operation.

2. Output Voltage Setting:

   • The output voltage can be adjusted using external resistors. Use the formula: [ V_{text} = V_{text} left(1 + fracright) ] where ( V_{text} ) is typically 1.25 V.

3. Output Current:

   • The device can provide up to 500 mA of continuous output current. Ensure the load does not exceed this limit to prevent overheating or damage.

4. Quiescent Current:

   • The quiescent current is very low, typically around 1.5 μA, which makes the BA10393N suitable for battery-powered applications.

5. Dropout Voltage:

   • The dropout voltage is the difference between the input and output voltages at maximum load. It is typically around 150 mV to 300 mV, allowing the regulator to operate efficiently even at low input voltages.

6. Power Supply Rejection Ratio (PSRR):

   • The PSRR indicates how well the regulator rejects variations in the input voltage. A higher PSRR value means better rejection of noise and ripple from the input.

7. Load and Line Regulation:

   • Both load and line regulation are specified as a percentage change in output voltage. These parameters ensure that the output voltage remains stable under varying load and input conditions.

8. Operating and Storage Temperature:

   • The device is designed to operate over a wide temperature range (-40°C to 85°C). For long-term storage, keep the device within the storage temperature range (-55°C to 150°C).

9. PCB Layout Considerations:

   • Place the input and output capacitors close to the IC to minimize noise and improve stability.
   • Use a ground plane to help dissipate heat and reduce electromagnetic interference (EMI).

10. Protection Features:

    • The BA10393N includes thermal shutdown and short-circuit protection to safeguard the device under fault conditions.

By following these instructions and adhering to the specified parameters, you can ensure reliable and efficient operation of the BA10393N linear regulator.
