LM2903AVQDRQ1 datasheet by Texas Instruments

LM2903AVQDRQ1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2903AVQDRQ1 can handle?
  The maximum input voltage for the LM2903AVQDRQ1 is 26V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be between 0.5 ohms and 10 ohms.
• What is the dropout voltage of the LM2903AVQDRQ1?
  The dropout voltage of the LM2903AVQDRQ1 is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
• Can I use the LM2903AVQDRQ1 in a high-temperature environment?
  The LM2903AVQDRQ1 is rated for operation up to 125°C, but the output current should be derated for temperatures above 85°C to prevent overheating.
• How do I calculate the power dissipation of the LM2903AVQDRQ1?
  The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
