Instructions for Use:
Input Capacitor:
- A 1μF ceramic capacitor is recommended at the input for stability and transient response.
Output Capacitor:
- A 1μF ceramic capacitor is recommended at the output to ensure stability and proper regulation.
PCB Layout:
- Keep the PCB traces from the input and output capacitors to the regulator as short as possible to minimize noise and improve transient response.
Thermal Considerations:
- Ensure adequate heat sinking if operating near maximum load conditions to prevent overheating.
Operation Range:
- The device operates within an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.3V.
Handling Precautions:
- Handle with care to avoid damage to the leads and body. Follow ESD (Electrostatic Discharge) precautions when handling.
Mounting:
- Mount the component on the PCB using standard surface mount technology (SMT) processes. Ensure that the orientation matches the silkscreen on the PCB.
