LM723H Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM723H can handle?
  The LM723H can handle input voltages up to 40V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
• How do I adjust the output voltage of the LM723H?
  The output voltage of the LM723H can be adjusted by connecting a resistor divider network between the output pin and the adjustment pin. The ratio of the resistors determines the output voltage.
• What is the minimum load current required for the LM723H to regulate properly?
  The LM723H requires a minimum load current of 10mA to regulate properly. If the load current is less than 10mA, the output voltage may not be regulated accurately.
• Can I use the LM723H in a switching regulator application?
  No, the LM723H is a linear voltage regulator and is not designed for use in switching regulator applications. It's intended for use in linear power supply applications.
• How do I protect the LM723H from overheating?
  To protect the LM723H from overheating, ensure that the device is mounted on a heat sink with a thermal resistance of less than 50°C/W. Also, keep the input voltage and output current within the recommended limits.
