LM309H/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM309H is 35V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure a stable output voltage, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum load current of 5mA. Also, keep the input voltage ripple low and use a low-ESR capacitor.
  • The LM309H is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermally-enhanced package (e.g., TO-220) for high-temperature applications.
  • Use a transient voltage suppressor (TVS) diode or a voltage clamp circuit to protect the LM309H from input voltage transients. This will help prevent damage from voltage spikes or surges.
  • No, the LM309H is a linear voltage regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
