LP2951-30D datasheet by Texas Instruments

LP2951-30D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2951-30D?
  The maximum input voltage that can be applied to the LP2951-30D is 30V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the LP2951-30D is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF, and keep the output capacitor's ESR (Equivalent Series Resistance) below 5 ohms. Also, avoid using long, thin traces for the output capacitor connections.
• What is the minimum input voltage required for the LP2951-30D to regulate properly?
  The minimum input voltage required for the LP2951-30D to regulate properly is around 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the LP2951-30D in a high-temperature environment?
  The LP2951-30D is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and consider using a heat sink if operating in high-temperature environments.
• How do I calculate the output voltage tolerance of the LP2951-30D?
  The output voltage tolerance of the LP2951-30D is typically ±2% over the entire operating temperature range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (3.0V) by the tolerance percentage (2%).
