Instructions for STR3123

1. Input Connection:

   • Connect the input voltage (V_IN) to the IN pin.
   • Ensure the input voltage is within the range of 2.7V to 5.5V.

2. Output Connection:

   • Connect the output load to the OUT pin.
   • The output voltage can be adjusted by using external resistors if required.

3. Ground Connection:

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

4. Capacitors:

   • Place a 1μF ceramic capacitor between the IN pin and GND as close to the device as possible.
   • Place a 10μF electrolytic capacitor between the OUT pin and GND to stabilize the output.

5. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high output currents.
   • Use a heatsink if necessary, especially when the ambient temperature is high.

6. Adjusting Output Voltage:

   • The output voltage can be adjusted using the following formula: [ V_ = 1.25 left(1 + fracright) ]
   • Where ( R_1 ) and ( R_2 ) are the resistors connected between the ADJ pin, GND, and OUT.

7. Enabling/Disabling:

   • The EN pin can be used to enable or disable the regulator.
   • Apply a high logic level to the EN pin to enable the regulator.
   • Apply a low logic level to the EN pin to disable the regulator.

8. Protection Features:

   • The device includes overcurrent protection and thermal shutdown to prevent damage under fault conditions.

9. Storage and Handling:

   • Store the device in a dry, cool place.
   • Handle with care to avoid static discharge, which can damage the device.

10. Mounting:

    • Solder the device to the PCB using standard surface mount technology (SMT) processes.
    • Ensure all connections are secure and free from solder bridges.
