Instructions for Use:
Input Connection:
- Connect the input voltage (VIN) to the positive terminal of the power supply.
- Ensure the input voltage is within the specified range (2.7V to 5.5V).
Output Connection:
- Connect the output voltage (VOUT) to the load or circuit requiring a regulated 3.3V supply.
- The output can provide up to 400mA of continuous current.
Ground Connection:
- Connect the ground (GND) pin to the common ground of the system.
Capacitors:
- Place a 1uF ceramic capacitor between VIN and GND as close to the device as possible to filter input noise.
- Place a 1uF ceramic capacitor between VOUT and GND to stabilize the output.
Thermal Management:
- Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
- The device is designed to operate within the specified temperature range (-40°C to 85°C).
PCB Layout:
- Use a ground plane to improve thermal performance and reduce noise.
- Keep traces short and wide to minimize inductance and resistance.
Storage:
- Store the device in a dry environment within the storage temperature range (-65°C to 150°C).
Handling:
- Handle with care to avoid damage to the leads and package.
- Follow ESD (Electrostatic Discharge) precautions to prevent damage to the device.
