Power Supply Connection:
- Connect the input voltage (VIN) between 2.7V and 5.5V to the IN pin.
- Ensure a stable power supply to prevent damage or malfunction.
Output Configuration:
- The output voltage (VOUT) is fixed at 3.3V. No external resistors are required for setting the output voltage.
Current Handling:
- The device can provide up to 3.0A of continuous output current with typical performance at 1.5A.
Quiescent and Shutdown Current:
- In normal operation, the quiescent current is typically 2.0μA.
- To minimize power consumption, use the shutdown feature by pulling the SHDN pin low, which reduces the current to approximately 0.1μA.
Thermal Considerations:
- Operate within the junction temperature range of -40°C to 125°C.
- Ensure adequate heat dissipation if operating near maximum current and temperature limits.
Dropout Voltage:
- At an output current of 300mA, the dropout voltage is typically 250mV. Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.
Capacitor Selection:
- Use appropriate input and output capacitors as specified in the datasheet to ensure stability and proper operation.
