Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (V_IN) within the operating range of 2.7V to 5.5V.
   • Ensure proper bypass capacitors are placed close to the input and output pins for stability.

2. Output Configuration:

   • The APT1002R4BN provides a fixed output voltage of 3.3V.
   • Do not exceed the maximum output current of 200mA to avoid damage.

3. Quiescent and Dropout Considerations:

   • The quiescent current is typically 1.6渭A at an input voltage of 5V with no load.
   • The dropout voltage is typically 0.4V at an output current of 100mA, ensuring efficient operation even at lower input voltages.

4. Shutdown Functionality:

   • To disable the regulator, pull the SHDN pin low. This will reduce the current consumption to approximately 0.1渭A.
   • To enable the regulator, ensure the SHDN pin is high or left floating.

5. Temperature Management:

   • Operate the device within the temperature range of -40掳C to +85掳C.
   • Avoid exposing the device to temperatures outside this range to prevent malfunction or damage.

6. Layout Recommendations:

   • Place the input and output capacitors as close as possible to the respective pins to minimize noise and improve transient response.
   • Ensure adequate PCB trace widths to handle the output current without excessive resistance or heating.
