Instructions for Use:
Power Supply Connection:
- Connect the input voltage (VIN) to the VIN pin.
- Ensure the input voltage is within the specified range of 2.7V to 5.5V.
Output Configuration:
- The output voltage (VOUT) is fixed at 3.3V. No external resistors are required for this setting.
Load Connection:
- Connect the load to the VOUT pin. The maximum continuous output current is 1.5A.
Quiescent and Shutdown Current:
- The quiescent current (IQ) is typically 200μA when no load is connected.
- To put the device into shutdown mode, pull the SHDN pin low. The shutdown current (ISD) is typically 1μA.
Efficiency:
- The efficiency (η) is typically 90% at full load (1.5A) with an input voltage of 5V.
Dropout Voltage:
- The dropout voltage (VDROP) is typically 300mV at full load (1.5A) and an input voltage of 5V.
Temperature Considerations:
- The operating temperature range (TOP) is from -40°C to 85°C.
- The storage temperature range (TSTORAGE) is from -65°C to 150°C.
Capacitors:
- Use appropriate input and output capacitors to ensure stability and reduce ripple. Refer to the datasheet for specific capacitor recommendations.
PCB Layout:
- Follow the recommended PCB layout guidelines to minimize noise and improve thermal performance. Keep the input and output capacitors close to the respective pins.
Handling:
- Handle the device with care to avoid damage from electrostatic discharge (ESD). Use proper ESD protection measures during handling and installation.
