Instructions for Using DTC144EK
Supply Voltage:
- Ensure the supply voltage is within the range of 2.7V to 5.5V.
- Use a stable power source to avoid fluctuations that could affect performance.
Quiescent Current:
- The typical quiescent current is 20 μA, which is relatively low, making it suitable for battery-operated devices.
Output Current:
- The maximum continuous output current is 150 mA. Do not exceed this limit to prevent damage to the device.
Output Voltage:
- The nominal output voltage is fixed at 3.3V. This is suitable for powering 3.3V logic circuits.
Dropout Voltage:
- The typical dropout voltage is 120 mV at a load current of 150 mA. This means the input voltage should be at least 3.42V to maintain a 3.3V output.
Load Regulation:
- The change in output voltage due to load variations is typically 0.5%. This ensures stable output under varying load conditions.
Line Regulation:
- The change in output voltage due to input voltage variations is typically 0.1%. This ensures stable output even if the input voltage fluctuates.
Thermal Shutdown:
- The device will shut down if the temperature exceeds 160°C to protect against overheating. Allow the device to cool before resuming operation.
Operating Temperature:
- The operating temperature range is from -40°C to 85°C. Ensure the device is used within this range to avoid performance degradation or damage.
Storage Temperature:
- The storage temperature range is from -65°C to 150°C. Store the device in a dry place to prevent moisture damage.
PCB Layout:
- Use a proper PCB layout with adequate heat dissipation to ensure reliable operation. Place the device away from heat sources and use a heatsink if necessary.
Capacitors:
- Use appropriate input and output capacitors to stabilize the supply and output voltages. Typical values are 1 μF for both input and output.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal components. Use ESD protection when handling the device.
By following these parameters and instructions, you can ensure optimal performance and reliability of the DTC144EK regulator.
