Instructions for Use
Circuit Design:
- Ensure that the input voltage is within the specified range (4.5V to 30V).
- Select the appropriate output voltage option (3.3V, 5V, or adjustable).
- For adjustable output voltage, use external resistors to set the desired output voltage.
Capacitor Selection:
- Use a 1μF ceramic capacitor on the input side for stability.
- Use a 1μF ceramic capacitor on the output side for stability and transient response.
Thermal Considerations:
- Ensure adequate heat dissipation if operating at high output currents or high ambient temperatures.
- The device has built-in thermal shutdown protection to prevent damage from excessive temperature.
Layout Recommendations:
- Place the input and output capacitors as close as possible to the device to minimize parasitic inductance.
- Use wide and short traces for power and ground connections to reduce resistance and inductance.
Handling Precautions:
- Handle the device with care to avoid damage from electrostatic discharge (ESD).
- Follow proper soldering techniques to ensure reliable connections.
Testing:
- Before finalizing the design, test the circuit under various conditions to ensure stable operation and compliance with specifications.
