Instructions:
- Supply Voltage (Vcc): Ensure the supply voltage is within the specified range of 2.7V to 5.5V to avoid damage or improper operation.
- Quiescent Current (IQ): The device consumes approximately 10 μA when no load is applied.
- Output Current (Iout): The maximum continuous output current is 100 mA. Do not exceed this limit to prevent overheating and potential damage.
- Output Voltage (Vout): The regulated output voltage is typically 3.3V. Verify this with your application requirements.
- Dropout Voltage (Vdo): The dropout voltage is typically 0.3V. This means the input voltage must be at least 0.3V higher than the output voltage for proper regulation.
- Load Regulation: The output voltage changes by less than 0.1% with varying loads.
- Line Regulation: The output voltage changes by less than 0.05% with varying input voltages.
- Ripple Rejection: The device can attenuate input ripple by up to 70 dB.
- Thermal Shutdown (TSD): The device will shut down if the temperature exceeds 160°C to protect against thermal damage.
- Operating Temperature (Ta): The device is designed to operate in ambient temperatures ranging from -40°C to 85°C.
- Storage Temperature (Tstg): Store the device in temperatures ranging from -65°C to 150°C.
Additional Notes:
- Always use appropriate decoupling capacitors on the input and output to ensure stable operation.
- For high current applications, consider adding heat sinking to manage thermal dissipation.
- Refer to the datasheet for detailed information on pin configurations, package types, and specific application notes.
