Instructions for Using BA10358N
Input Voltage:
- Ensure the input voltage is within the specified range (2.7V to 5.5V). Exceeding this range can damage the device.
Output Voltage:
- The BA10358N provides a fixed output voltage of 3.3V. No external components are required to set this voltage.
Output Current:
- The device can deliver up to 500mA continuously. For higher currents, consider using a heatsink or ensuring adequate thermal management.
Quiescent Current:
- The quiescent current is very low, typically around 4.0μA, which makes it suitable for battery-powered applications.
Dropout Voltage:
- The dropout voltage is relatively low, ranging from 200mV to 300mV at 500mA. This allows the regulator to operate efficiently even when the input voltage is close to the output voltage.
PSRR:
- The power supply rejection ratio (PSRR) is 70dB at 1kHz, indicating good noise suppression capabilities.
Load and Line Regulation:
- The load regulation is 0.1% to 0.5%, and the line regulation is 0.05% to 0.1%. These values ensure stable output voltage under varying load and input conditions.
Operating Temperature:
- The device operates reliably over a wide temperature range from -40°C to 85°C. For extended storage, the temperature range is -55°C to 150°C.
Thermal Management:
- If operating near the maximum output current, ensure proper heat dissipation to prevent overheating. Use a heatsink if necessary.
Circuit Design:
- Connect the input and output capacitors as recommended in the datasheet to ensure stability and filter out noise. Typically, a 1μF ceramic capacitor on both the input and output is sufficient.
PCB Layout:
- Place the input and output capacitors as close as possible to the respective pins of the BA10358N to minimize parasitic inductance and improve performance.
By following these guidelines, you can ensure optimal performance and reliability of the BA10358N in your application.
