LM339PWR datasheet by Texas Instruments

LM339PWR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM339PWR?
  The maximum power dissipation of the LM339PWR is 1000mW (1W) when mounted on a 50mm x 50mm, 2oz copper PCB.
• Can I use the LM339PWR as a comparator with hysteresis?
  Yes, the LM339PWR can be used as a comparator with hysteresis by adding positive feedback through a resistor and capacitor network.
• How do I ensure stability when using the LM339PWR as an oscillator?
  To ensure stability when using the LM339PWR as an oscillator, use a capacitor with a low equivalent series resistance (ESR) and a high-quality inductor with a low series resistance.
• What is the maximum input voltage that can be applied to the LM339PWR?
  The maximum input voltage that can be applied to the LM339PWR is 36V, but it's recommended to keep the input voltage below 30V for reliable operation.
• Can I use the LM339PWR as a voltage regulator?
  No, the LM339PWR is not designed to be used as a voltage regulator. It's a quad comparator, not a voltage regulator.
