LP339N/NOPB datasheet by Texas Instruments

LP339N/NOPB Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LP339N/NOPB?
  The LP339N/NOPB can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure the LP339N/NOPB is stable and doesn't oscillate?
  To ensure stability, use a capacitor with a value between 10nF to 100nF between the output and the adjust pin, and a resistor with a value between 1kΩ to 10kΩ between the output and the input.
• What is the minimum input voltage required for the LP339N/NOPB to function properly?
  The minimum input voltage required is 2.7V, but it's recommended to use a minimum of 3V to ensure proper operation.
• Can I use the LP339N/NOPB as a voltage regulator for high-current applications?
  No, the LP339N/NOPB is not designed for high-current applications. It's recommended to use a dedicated voltage regulator IC for high-current applications.
• How do I calculate the output voltage of the LP339N/NOPB?
  The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (1.24V), R1 is the resistor between the output and the adjust pin, and R2 is the resistor between the output and the input.
