LM2903AVQDRG4 datasheet by Texas Instruments

LM2903AVQDRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2903AVQDRG4 can handle?
  The maximum input voltage for the LM2903AVQDRG4 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 LM2903AVQDRG4?
  The dropout voltage of the LM2903AVQDRG4 is typically around 1.5V to 2V, depending on the output current and input voltage.
• Can I use the LM2903AVQDRG4 in a high-temperature environment?
  The LM2903AVQDRG4 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Thermal management is crucial in high-temperature environments.
• How do I calculate the power dissipation of the LM2903AVQDRG4?
  Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and maximum junction temperature when calculating power dissipation.
