Instructions for TPS72301DBVR

1. Input Voltage Setup:

   • Ensure the input voltage (VIN) is within the range of 1.6V to 5.5V. This device can operate over a wide input voltage range, but exceeding these limits may damage the component.

2. Output Voltage Configuration:

   • The output voltage (VOUT) is adjustable between 0.8V and 3.3V. Use external resistors to set the desired output voltage according to the formula provided in the datasheet.

3. Quiescent Current Consideration:

   • The quiescent current is typically 24μA at VIN = 3.3V and VOUT = 1.8V. Design your circuit considering this current consumption to ensure efficient power management.

4. Dropout Voltage Awareness:

   • The dropout voltage is around 170mV at an output current of 100mA. Keep this in mind when designing circuits where the difference between input and output voltages is minimal.

5. Load and Line Regulation:

   • The load regulation is very tight at 0.5%, ensuring stable output under varying load conditions. The line regulation of 0.01%/V ensures stability with changes in input voltage.

6. Power Supply Rejection Ratio (PSRR):

   • With a PSRR of 60dB at 1kHz, this regulator effectively suppresses ripple from the input supply, providing clean output.

7. Transient Response:

   • The transient response is about 100mV for a step change from 0mA to 100mA. Ensure your design can handle this voltage deviation during load transients.

8. Operating Temperature Range:

   • Operate the device within the temperature range of -40°C to 85°C to maintain reliability and performance.

9. PCB Layout Recommendations:

   • Follow recommended PCB layout guidelines to minimize noise and improve thermal performance. Place the input and output capacitors as close as possible to the regulator to enhance stability.

10. Capacitor Selection:

    • Choose appropriate input and output capacitors based on the manufacturer's recommendations to ensure stability and proper operation.
