Instructions for IPS5451:

1. Input Voltage (VIN):

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

2. Output Voltage (VOUT):

   • The output voltage is fixed at 3.3V and does not require external components for setting the voltage.

3. Quiescent Current:

   • When no load is applied (IOUT = 0mA), the quiescent current is typically 1.8μA.

4. Shutdown Mode:

   • To enter shutdown mode, pull the SHDN pin to ground. In this mode, the shutdown current is approximately 0.1μA.

5. Load Regulation:

   • The load regulation is maintained at ±0.1% from 10mA to 200mA output current.

6. Line Regulation:

   • Line regulation is also ±0.1% over the input voltage range from 2.7V to 5.5V.

7. Dropout Voltage:

   • At a maximum output current of 200mA, the dropout voltage is typically 0.3V.

8. Maximum Output Current:

   • The device can supply up to 200mA of output current when VIN is 5V and VOUT is 3.3V.

9. Application Considerations:

   • Use appropriate decoupling capacitors on both input and output to ensure stability.
   • Ensure adequate heat sinking if operating near maximum output current to prevent overheating.

10. Storage and Handling:

    • Store in a dry environment and handle with care to avoid damage to the sensitive electronic components.
