LM26003MH/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
  • To ensure the LM26003MH/NOPB operates within its SOA, monitor the input voltage, output current, and junction temperature. Make sure the input voltage is within the recommended range, the output current is within the maximum rating, and the junction temperature is below the maximum rating of 150°C.
  • The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric. The value depends on the input voltage and output current, but a typical value is 10uF to 22uF.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
  • The maximum ambient temperature range for the LM26003MH/NOPB is -40°C to 125°C, but the device can operate up to 150°C junction temperature.
