Instructions for Use:
Power Supply:
- Ensure the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
- Connect the input capacitor (CIN) close to the input pin to stabilize the supply.
Output Configuration:
- The output voltage (Vout) will be regulated to the specified value, typically 3.3V or 5V depending on the model.
- Place an output capacitor (COUT) close to the output pin to maintain stability and reduce ripple.
Thermal Management:
- Monitor the operating junction temperature (Tjop) to ensure it does not exceed 150°C.
- If the device reaches the thermal shutdown temperature (TSD), it will automatically turn off to prevent damage.
Load Handling:
- The device can provide up to 150mA of continuous output current (Iout).
- For higher current requirements, consider using additional external components or a different regulator.
Storage and Handling:
- Store the device in a controlled environment with temperatures between -65°C and 150°C (Tstg).
- Handle with care to avoid static discharge, which can damage the component.
Capacitor Selection:
- Use ceramic capacitors with X7R dielectric for CIN and COUT.
- Typical values for CIN and COUT are 1μF and 10μF, respectively, but consult the datasheet for specific recommendations.
PCB Layout:
- Place the regulator close to the load to minimize trace inductance and improve performance.
- Use wide and short traces for power and ground connections to reduce resistance and inductance.
