LP339MX/NOPB datasheet by Texas Instruments

LP339MX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LP339MX/NOPB?
  The LP339MX/NOPB can operate from -40°C to 125°C, making it suitable for a wide range of applications.
• How do I ensure the LP339MX/NOPB is stable and doesn't oscillate?
  To ensure stability, it's essential to follow proper PCB layout practices, use a low-ESR capacitor for the output filter, and avoid using a capacitor with high equivalent series resistance (ESR) for the input filter.
• What is the recommended input capacitor value for the LP339MX/NOPB?
  The recommended input capacitor value is 1-10 μF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input voltage ripple.
• Can I use the LP339MX/NOPB in a high-reliability application?
  Yes, the LP339MX/NOPB is suitable for high-reliability applications due to its high MTBF (mean time between failures) rating and compliance with various industry standards, such as AEC-Q100.
• How do I calculate the output voltage of the LP339MX/NOPB?
  The output voltage of the LP339MX/NOPB can be calculated using the formula: Vout = (1 + R1/R2) * Vref, where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (1.24 V).
