Instructions for Use

1. Input Power Supply:

   • Ensure the input voltage is within the specified range of 2.7V to 5.5V.

2. Output Configuration:

   • For fixed output versions, no external components are required for setting the output voltage.
   • For adjustable versions, use external resistors to set the desired output voltage as per the datasheet formula.

3. Capacitor Selection:

   • Choose input and output capacitors that meet the stability criteria specified in the datasheet.
   • Recommended ceramic capacitors with X5R or X7R dielectric types.

4. Thermal Considerations:

   • Ensure adequate heat sinking if operating near maximum load conditions.
   • Check thermal resistance values and ambient temperature limits.

5. Enable/Shutdown Control:

   • Apply a logic high to the enable pin to activate the regulator.
   • Pull the enable pin low to put the device into shutdown mode, reducing power consumption.

6. Protection Features:

   • The device includes overcurrent and overtemperature protection circuits to safeguard against fault conditions.

7. Layout Guidelines:

   • Follow recommended PCB layout practices to minimize noise and ensure stable operation.
   • Keep input and output capacitors close to the device pins.
