LM1117MPX-3.3 Frequently Asked Questions (FAQ)

  • The maximum input voltage is 15V, but it's recommended to keep it below 13.5V for reliable operation.

  • The LM1117MPX-3.3 is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.

  • Use a high-quality output capacitor (e.g., 10uF ceramic) and ensure the input voltage is well-regulated. Also, minimize noise and ripple on the input voltage to ensure a stable output.

  • Yes, the LM1117MPX-3.3 is suitable for battery-powered devices. However, consider the quiescent current (IQ) and dropout voltage (VD) to minimize power consumption and ensure efficient battery life.

  • The minimum input voltage required for proper regulation is around 4.5V, but it's recommended to keep it above 5V for optimal performance.
