Instructions for Use:
Input Voltage (VIN):
- Ensure the input voltage is within the specified range of 4.5 V to 26 V to avoid damage to the device.
Output Voltage (VOUT):
- The device provides a fixed output voltage of 3.3 V. No external components are required to set this voltage.
Output Current (IOUT):
- The maximum continuous output current is 1.5 A. Ensure that the load does not exceed this limit to prevent overheating or damage.
Quiescent Current (IQ):
- The typical quiescent current is 70 μA. This value is important for low-power applications to minimize power consumption.
Dropout Voltage (VDROPOUT):
- The typical dropout voltage is 350 mV at full load (1.5 A). Ensure that the input voltage is at least 350 mV higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is 0.5%, indicating that the output voltage will change by 0.5% for a change in load current.
Line Regulation:
- The line regulation is 0.01% per volt, indicating that the output voltage will change by 0.01% for each volt change in input voltage.
Thermal Shutdown (TSD):
- The device will shut down if the junction temperature reaches approximately 160°C to protect against thermal damage.
Operating Junction Temperature (TJ):
- The operating junction temperature range is from -20°C to 150°C. Ensure that the device operates within this range to avoid performance issues or damage.
Storage Temperature (TSTG):
- The storage temperature range is from -65°C to 150°C. Store the device within this range to ensure its reliability and performance.
Additional Considerations:
- Capacitors:
- Use appropriate input and output capacitors as recommended in the datasheet to ensure stability and reduce noise.
- PCB Layout:
- Follow good PCB layout practices to minimize parasitic inductance and ensure proper heat dissipation.
- Heat Sinking:
- If operating at high currents or in high ambient temperatures, consider using a heat sink to improve thermal performance.
