Instructions for Use:

1. Power Supply:

   • Connect the supply voltage (Vcc) to the input pin.
   • Ensure the supply voltage is within the range of 4.5V to 5.5V.

2. Output Connection:

   • Connect the load to the output pin (Vout).
   • The output voltage is regulated to 3.3V and can supply up to 100mA.

3. Ground Connection:

   • Connect the ground (GND) pin to the system ground.

4. Standby Mode:

   • To enter standby mode, set the enable pin (EN) to low.
   • In standby mode, the current consumption is reduced to approximately 1μA.

5. Operating Conditions:

   • The device operates over a temperature range of -40°C to 85°C.
   • Store the device in temperatures ranging from -55°C to 125°C.

6. Capacitors:

   • Place a 10μF tantalum capacitor close to the input pin for stability.
   • Place a 10μF ceramic capacitor close to the output pin to filter out noise.

7. PCB Layout:

   • Ensure proper PCB layout with short traces and adequate grounding to minimize noise and improve performance.

8. Handling:

   • Handle the device with care to avoid static damage.
   • Follow ESD (Electrostatic Discharge) precautions during handling and installation.
