Instructions for RT6903BZQV
Power Supply Connection:
- Connect the input voltage (VIN) between 2.5V and 5.5V to the IN pin.
- Ensure proper bypassing with a capacitor (e.g., 1μF ceramic) close to the IN pin.
Output Voltage Setting:
- The output voltage can be adjusted using external resistors connected to the FB pin. Refer to the datasheet for specific resistor values based on desired output voltage.
Ground Connection:
- Ensure a solid ground connection for both input and output capacitors as well as the GND pin of the device.
Load Considerations:
- The device can supply up to 300mA. For higher currents, ensure adequate heat sinking or consider a different regulator.
Thermal Management:
- Operate within the specified temperature range (-40°C to 85°C). Use a heatsink if operating at high temperatures or under high load conditions.
Stability:
- Use output capacitors with ESR in the recommended range to ensure stability. A typical value is 1μF to 10μF ceramic capacitor.
Protection Features:
- The device includes overcurrent and thermal shutdown protection. Verify these features are suitable for your application.
Layout Recommendations:
- Keep the PCB layout compact, minimizing trace lengths between the regulator and its capacitors to reduce noise and improve transient response.
