LM117H/NOPB Frequently Asked Questions (FAQs)

  • The LM117H can handle input voltages up to 42V, but it's recommended to keep it below 35V 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 LM117H 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 voltage clamp or a transient voltage suppressor (TVS) diode at the input to protect the LM117H from voltage surges or spikes. You can also add a series resistor and a capacitor to filter out high-frequency noise.
  • Yes, the LM117H is suitable for battery-powered devices. However, consider the quiescent current (IQ) and the dropout voltage (VD) to ensure efficient battery life. You may also want to add a low-battery detector or a power-management IC to optimize battery life.
