LF398MX/NOPB Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the LF398MX/NOPB is 10V to 36V, with a maximum rating of 40V.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be located close to the output pin. Additionally, a 1uF capacitor can be added between the input and ground pins to improve stability.
  • The maximum output current of the LF398MX/NOPB is 1A, but it can be limited by the input voltage, output voltage, and thermal considerations.
  • To protect the LF398MX/NOPB from overheating, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and avoid operating the device at maximum power dissipation for extended periods.
  • No, the LF398MX/NOPB is designed for positive voltage regulation only. For negative voltage regulation, a different device such as the LM337 or TLV7031 should be used.
