Instructions for Using STBV32
Input Voltage:
- Ensure the input voltage is within the specified range of 2.7V to 5.5V.
- Use a suitable decoupling capacitor (typically 1μF to 10μF) between the input and ground to filter out noise.
Output Voltage:
- The output voltage is fixed at 3.3V. No external components are required to set this voltage.
Output Current:
- The device can provide up to 300mA of continuous output current. For higher currents, consider using a heatsink or a more powerful regulator.
Quiescent Current:
- The quiescent current is typically 10μA, which is very low, making the device suitable for battery-powered applications.
Dropout Voltage:
- The dropout voltage is approximately 300mV at full load (300mA). This means the input voltage should be at least 3.6V to maintain the 3.3V output.
Load Regulation:
- The change in output voltage due to load variations is typically 10mV. This ensures stable output even under varying load conditions.
Line Regulation:
- The change in output voltage due to input voltage variations is also typically 10mV, ensuring stable output over the input voltage range.
Ripple Rejection:
- The power supply rejection ratio (PSRR) is 60dB, effectively filtering out input ripple and noise.
Operating Temperature:
- The device operates reliably from -40°C to 85°C. Ensure proper thermal management if operating near the upper limit.
Storage Temperature:
- Store the device in a temperature range of -55°C to 150°C to avoid damage.
PCB Layout:
- Place the input and output capacitors as close as possible to the regulator to minimize trace inductance and improve performance.
- Use wide traces for the input and output connections to reduce resistance and voltage drop.
Heatsinking:
- For high current applications, consider adding a heatsink to the regulator to dissipate heat and prevent overheating.
Protection:
- The device includes internal short-circuit and thermal shutdown protection to prevent damage under fault conditions.
By following these guidelines, you can ensure optimal performance and reliability of the STBV32 voltage regulator in your application.
