Instructions for Use
Input Voltage:
- Ensure the input voltage is within the specified range of 4.5V to 16V to avoid damage to the device.
Output Voltage:
- The device provides a regulated output voltage of 5.0V. Verify that this matches your application requirements.
Output Current:
- The device can provide a continuous output current up to 3.0A. For currents above 2.0A, ensure proper heat dissipation.
Quiescent Current:
- The quiescent current is typically 25μA and can go up to 50μA. This is important for low-power applications.
Dropout Voltage:
- The dropout voltage is typically 0.5V and can go up to 1.0V. Ensure the input voltage is at least this much higher than the output voltage to maintain regulation.
Line Regulation:
- The line regulation is typically 0.1% and can go up to 0.5%. This ensures stable output voltage despite variations in input voltage.
Load Regulation:
- The load regulation is typically 0.1% and can go up to 0.5%. This ensures stable output voltage despite variations in load current.
Ripple Rejection:
- The power supply rejection ratio (PSRR) is typically 60dB and can go up to 80dB. This helps in filtering out input ripple and noise.
Operating Temperature:
- The device can operate within a temperature range of -40°C to 125°C. Ensure adequate cooling if operating near the upper limit.
Storage Temperature:
- The device can be stored within a temperature range of -55°C to 150°C. Avoid exposing the device to extreme temperatures for extended periods.
Thermal Resistance:
- The junction-to-ambient thermal resistance is typically 40°C/W and can go up to 60°C/W. Use appropriate heatsinking if operating at high power levels or in high ambient temperatures.
Mounting:
- Mount the device on a PCB with proper thermal management techniques, such as using a heat sink or thermal vias, to ensure reliable operation.
Handling:
- Handle the device with care to avoid static discharge and physical damage. Follow ESD (Electrostatic Discharge) precautions during handling and installation.
Testing:
- Before final assembly, test the device under typical operating conditions to ensure it meets the required performance specifications.
