Instructions:
Power Supply Connection:
- Connect the input voltage (V_IN) to the input pin.
- Ensure the input voltage is within the specified range (4.5V to 28V).
Output Configuration:
- The output voltage (V_OUT) is fixed at 3.3V.
- Connect the output pin to your load.
Grounding:
- Connect the ground (GND) pin to the common ground of your circuit.
Thermal Management:
- Ensure proper heat dissipation, especially when operating at high output currents.
- Use a heatsink if necessary to keep the junction temperature below 160°C.
Capacitors:
- Place a 10μF tantalum capacitor or a 10μF ceramic capacitor between the input and ground pins close to the device.
- Place a 10μF tantalum capacitor or a 10μF ceramic capacitor between the output and ground pins close to the device.
Load Regulation:
- The load regulation is typically 1%, meaning the output voltage will change by 1% for variations in load current.
Line Regulation:
- The line regulation is typically 1%, meaning the output voltage will change by 1% for variations in input voltage.
Thermal Shutdown:
- The device will shut down if the junction temperature exceeds 160°C to prevent damage.
Operating and Storage Temperature:
- Ensure the device operates within the temperature range of -40°C to 125°C.
- Store the device within the temperature range of -65°C to 150°C.
Handling Precautions:
- Handle the device with care to avoid static damage.
- Follow proper soldering techniques to ensure reliable connections.
