LM2903ST Frequently Asked Questions (FAQs)

  • The LM2903ST can operate from -40°C to 125°C, making it suitable for a wide range of applications.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 5 ohms. Additionally, the input capacitor should be at least 10uF with an ESR of 5 ohms or less.
  • The minimum input voltage required for the LM2903ST is 7V, but it's recommended to use a minimum of 8V to ensure proper regulation.
  • While the LM2903ST can handle up to 1A of output current, it's essential to consider the thermal dissipation and heat sinking requirements to prevent overheating. A heat sink may be necessary for high-current applications.
  • To protect the LM2903ST from input voltage surges, it's recommended to use a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input.
