Instructions for Use
Input Voltage (VIN):
- Ensure the input voltage is within the specified range (4.5V to 20.0V).
- Use appropriate input capacitors to stabilize the input voltage.
Output Voltage (VOUT):
- Set the output voltage using external resistors according to the formula provided in the datasheet.
- Use a 1% tolerance resistor for better accuracy.
Output Current (IOUT):
- The maximum continuous output current is 2.0A. Ensure the load does not exceed this limit to avoid damage.
- Use a heatsink if operating at high currents to maintain safe operating temperatures.
Efficiency (η):
- The typical efficiency is 92% at full load. Monitor the power dissipation to ensure it remains within safe limits.
Dropout Voltage (VDO):
- The dropout voltage is typically 0.3V to 0.6V at 2A. Ensure the input voltage is always higher than the output voltage plus the dropout voltage.
Quiescent Current (IQ):
- The quiescent current is typically 50μA to 100μA. This should be considered when designing low-power systems.
Load Regulation:
- The load regulation is typically 0.5% to 1.0%. This indicates how much the output voltage changes with varying load conditions.
Line Regulation:
- The line regulation is typically 0.1% to 0.3% per volt. This indicates how much the output voltage changes with varying input voltage.
Ripple Rejection:
- The ripple rejection is typically 60dB to 70dB at 100kHz. This helps in filtering out input ripple and noise.
Operating Temperature (TOP):
- The operating temperature range is -40°C to 125°C. Ensure the device operates within this range to avoid thermal stress.
Storage Temperature (TSTG):
- The storage temperature range is -65°C to 150°C. Store the device in a dry, cool place to prevent damage.
Package Type:
- The device is available in SO-8 and SOT-23-5 packages. Choose the package type based on your PCB design requirements.
