Instructions for Use:
Supply Voltage (Vcc):
- Ensure the input voltage is within the range of 4.5V to 5.5V.
- Avoid exceeding the maximum supply voltage to prevent damage to the device.
Output Current (Iout):
- The device can provide up to 300mA of output current.
- For optimal performance, keep the load current within the typical range of 150mA.
Quiescent Current (Iq):
- The quiescent current is very low, typically around 1.0mA.
- This ensures minimal power consumption even when there is no load.
Dropout Voltage (Vdo):
- The dropout voltage is the difference between the input and output voltages when the device is under load.
- It should be kept below 1.0V for reliable operation.
Line Regulation:
- The line regulation is the change in output voltage due to changes in input voltage.
- It is typically very low, ensuring stable output voltage despite variations in input voltage.
Load Regulation:
- The load regulation is the change in output voltage due to changes in load current.
- It is also very low, ensuring stable output voltage as the load varies.
Thermal Shutdown Temperature (Tsd):
- The device will automatically shut down if the temperature exceeds 150°C to prevent damage.
- Ensure proper heat dissipation to avoid reaching this temperature.
Operating Temperature Range (Topr):
- The device can operate over a wide temperature range from -40°C to 125°C.
- For extended reliability, avoid operating at the extreme ends of this range.
Mounting and Layout:
- Use a good thermal design to ensure efficient heat dissipation.
- Place the device close to the load to minimize trace resistance and inductance.
Capacitors:
- Use appropriate bypass capacitors on both the input and output to stabilize the voltage and filter noise.
- Recommended values are typically 10μF for the input and 10μF for the output.
