LM117GW/883 datasheet by Texas Instruments

LM117GW/883 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM117GW/883 can handle?
  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?
  Use a 10uF capacitor on the input and a 22uF capacitor on the output, and ensure the input voltage is at least 2V higher than the output voltage.
• What is the minimum load current required for the LM117GW/883 to regulate properly?
  The minimum load current is 5mA, but it's recommended to have a load current of at least 10mA for optimal performance.
• Can I use the LM117GW/883 in a high-temperature environment?
  Yes, the LM117GW/883 is rated for operation up to 125°C, but the output current should be derated at higher temperatures to prevent overheating.
• How do I protect the LM117GW/883 from input voltage transients?
  Use a TVS diode or a transient voltage suppressor on the input to protect the regulator from voltage spikes and transients.
