LM26003QMHX/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the LM26003QMHX/NOPB datasheet, which includes a thermal pad connected to a copper plane on the PCB to dissipate heat. Additionally, it's recommended to use a 2-layer or 4-layer PCB with a solid ground plane to reduce thermal resistance.
  • To ensure the output voltage is stable and accurate, it's recommended to use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and a sufficient capacitance value. Additionally, the input voltage should be well-regulated and the device should be operated within its recommended operating conditions.
  • Although the datasheet specifies a maximum input voltage of 42V, it's recommended to derate the input voltage to 40V or less to ensure reliable operation and to prevent damage to the device.
  • The LM26003QMHX/NOPB has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it's still recommended to add external protection components such as fuses or current-limiting resistors to prevent damage to the device and the PCB.
  • The recommended input capacitor value is 10uF to 22uF, and it should be a low-ESR ceramic capacitor or a film capacitor with a voltage rating of at least 50V. The input capacitor helps to filter out noise and ripple on the input voltage.
