LM117HVK/883 datasheet by Texas Instruments

LM117HVK/883 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM117HVK/883?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  To ensure a stable output voltage, make sure to use a suitable output capacitor (at least 10uF) and a minimum load of 5mA. Also, keep the input voltage ripple low and use a low-ESR capacitor.
• Can I use the LM117HVK/883 in a high-temperature environment?
  The LM117HVK/883 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 if you expect high temperatures.
• How do I protect the LM117HVK/883 from input voltage surges?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the regulator from input voltage surges. You can also add a series resistor to limit the input current.
• Can I use the LM117HVK/883 in a switching regulator application?
  No, the LM117HVK/883 is a linear regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
