LM26LVQISD-130/NOPB datasheet by Texas Instruments

LM26LVQISD-130/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a PCB layout with a solid ground plane and a thermal pad connected to the ground plane to improve thermal performance. A minimum of 2oz copper thickness is recommended for the thermal pad.
• How do I ensure the device is not damaged during soldering?
  To prevent damage during soldering, Texas Instruments recommends following the recommended soldering profile, using a soldering iron with a temperature of 260°C or less, and avoiding excessive soldering time.
• What is the recommended input capacitor value and type for this device?
  Texas Instruments recommends using a 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric as the input capacitor. The capacitor should be placed as close as possible to the VIN pin.
• Can I use this device in a high-temperature environment?
  The LM26LVQISD-130/NOPB is rated for operation up to 125°C, but Texas Instruments recommends derating the output current and voltage at high temperatures to ensure reliable operation. Consult the datasheet for specific derating guidelines.
• How do I troubleshoot issues with the device not regulating the output voltage?
  To troubleshoot issues with the device not regulating the output voltage, check the input voltage, output load, and PCB layout for any errors or inconsistencies. Ensure that the input capacitor is properly sized and placed, and that the output voltage is within the specified range.
