LM723H/NOPB datasheet by Texas Instruments

LM723H/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM723H/NOPB can handle?
  The maximum input voltage for the LM723H/NOPB is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I adjust the output voltage of the LM723H/NOPB?
  The output voltage of the LM723H/NOPB can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
• What is the minimum input voltage required for the LM723H/NOPB to function?
  The minimum input voltage required for the LM723H/NOPB to function is 3V above the desired output voltage. For example, if you want a 5V output, the minimum input voltage should be at least 8V.
• Can I use the LM723H/NOPB in a high-temperature environment?
  The LM723H/NOPB is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I protect the LM723H/NOPB from input voltage transients?
  You can protect the LM723H/NOPB from input voltage transients by adding a transient voltage suppressor (TVS) diode or a zener diode between the input and ground. This will help absorb voltage spikes and prevent damage to the regulator.
