LM317AEMPX/NOPB datasheet by Texas Instruments

LM317AEMPX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM317AEMPX/NOPB can handle?
  The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I adjust the output voltage of the LM317AEMPX/NOPB?
  You can adjust the output voltage by using a resistor divider network between the output and adjustment pins. The formula is: Vout = 1.25 x (1 + R2/R1).
• What is the minimum load current required for the LM317AEMPX/NOPB to regulate properly?
  The minimum load current is 3.5mA, but it's recommended to have a load current of at least 10mA for stable operation.
• Can I use the LM317AEMPX/NOPB in a high-temperature environment?
  The LM317AEMPX/NOPB has an operating temperature range of -40°C to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink and ensure good airflow to keep the temperature below 85°C.
• How do I protect the LM317AEMPX/NOPB from input voltage transients?
  You can use a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor to protect the regulator from input voltage transients.
