LP2998MAX/NOPB datasheet by Texas Instruments

LP2998MAX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2998MAX/NOPB?
  The maximum input voltage that can be applied to the LP2998MAX/NOPB is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the minimum input voltage required for the LP2998MAX/NOPB to operate?
  The minimum input voltage required for the LP2998MAX/NOPB to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the LP2998MAX/NOPB in a high-temperature environment?
  The LP2998MAX/NOPB 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. It's essential to provide adequate heat sinking and thermal management to prevent overheating.
• How do I calculate the output voltage of the LP2998MAX/NOPB?
  The output voltage of the LP2998MAX/NOPB can be calculated using the following formula: Vout = 1.5V * (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
