LP2997M/NOPB datasheet by Texas Instruments

LP2997M/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2997M?
  The maximum input voltage that can be applied to the LP2997M is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the LP2997M is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a solid ground plane to reduce noise and oscillations.
• What is the minimum input voltage required for the LP2997M to operate?
  The minimum input voltage required for the LP2997M to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the LP2997M in a high-temperature environment?
  The LP2997M is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability. Make sure to provide adequate heat sinking and thermal management.
• How do I calculate the output voltage of the LP2997M?
  The output voltage of the LP2997M can be calculated using the formula: Vout = 1.2V * (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
