LP2951-33DRGR datasheet by Texas Instruments

LP2951-33DRGR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2951-33DRGR?
  The maximum input voltage that can be applied to the LP2951-33DRGR is 20V, but it's recommended to keep it below 18V for reliable operation.
• How do I ensure the LP2951-33DRGR is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output capacitor's ESR (Equivalent Series Resistance) below 1 ohm. Also, avoid using ceramic capacitors with high ESL (Equivalent Series Inductance).
• What is the minimum input voltage required for the LP2951-33DRGR to operate?
  The minimum input voltage required for the LP2951-33DRGR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the LP2951-33DRGR in a high-temperature environment?
  The LP2951-33DRGR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage tolerance of the LP2951-33DRGR?
  The output voltage tolerance of the LP2951-33DRGR is ±2% over the entire operating temperature range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (3.3V) by the tolerance percentage (±2%).
