Instructions for Use:

1. Power Supply:

   • Ensure the input voltage (VIN) is within the range of 2.7V to 5.5V.
   • The output voltage (VOUT) can be set between 0.8V and 3.6V using external resistors.

2. Output Current:

   • The device can provide a continuous output current up to 1.5A, with a peak of 2.0A.

3. Quiescent Current:

   • The quiescent current (IQ) is typically 20渭A when there is no load.

4. Shutdown Mode:

   • To put the device into shutdown mode, set the enable pin (VEN) to 0V. The shutdown current (ISD) is typically 0.1渭A.

5. Dropout Voltage:

   • The dropout voltage (VDROPOUT) is typically 150mV at an output current of 1.5A.

6. PSRR (Power Supply Rejection Ratio):

   • The device has a PSRR of 70dB at 1kHz, which helps in reducing noise from the power supply.

7. Regulation:

   • The line regulation is 0.05%/V, and the load regulation is 0.05%/A, ensuring stable output under varying conditions.

8. Thermal Protection:

   • The device includes thermal shutdown protection, which activates at approximately 160掳C.

9. Operating Temperature:

   • The operating temperature range is from -40掳C to 85掳C.

10. Capacitors:

    • Use appropriate input and output capacitors to ensure stability and filter out noise. Typically, 1渭F ceramic capacitors are recommended for both input and output.

11. Layout Considerations:

    • Keep the input and output capacitors close to the device to minimize inductance and improve transient response.

12. Enabling the Device:

    • To enable the device, apply a high logic level (typically 1.8V to 5.5V) to the enable pin (VEN).

13. Output Voltage Setting:

    • The output voltage can be adjusted using a voltage divider network connected to the feedback pin (FB). Refer to the datasheet for specific resistor values.

14. Stability:

    • Ensure that the loop compensation is properly designed to maintain stability over the entire operating range.
