Instructions for TPS767D318PWP:

1. Input Power Supply: Ensure the input voltage is within the specified range of 2.7V to 5.5V.
2. Output Configuration:
   • VOUT1 provides a fixed 3.3V output.
   • VOUT2 provides a fixed 1.8V output.
3. Thermal Considerations: Operate within the temperature range of -20°C to +85°C. Use proper heat sinking if operating near maximum temperatures or under high load conditions.
4. Capacitor Selection:
   • Input Capacitor: Place a 1μF ceramic capacitor close to the input pin to ensure stability and reduce noise.
   • Output Capacitors: For each output, place a 1μF ceramic capacitor close to the respective output pin to stabilize the output voltage.
5. PCB Layout:
   • Keep traces short and wide to minimize inductance and resistance.
   • Place capacitors as close as possible to the IC pins to improve performance.
6. Load Regulation: The device maintains tight load regulation, ensuring minimal variation in output voltage across different load conditions.
7. Line Regulation: Minimal change in output voltage due to variations in input voltage, enhancing stability in varying input conditions.
8. Power Supply Rejection Ratio (PSRR): The device effectively rejects input ripple, providing cleaner output voltages.
