LM7805CT Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM7805CT is 35V, but it's recommended to keep it below 25V for reliable operation.

  • The LM7805CT is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink or ensure good airflow to keep the temperature below 100°C.

  • To ensure stability, use a minimum of 0.33uF capacitor at the input and a minimum of 0.1uF capacitor at the output. Also, keep the leads as short as possible and use a good quality PCB layout.

  • No, the LM7805CT is designed to regulate positive voltages only. If you need to regulate a negative voltage, you'll need a different voltage regulator, such as the LM7905.

  • The LM7805CT can operate with a minimum load current of 5mA, but it's recommended to have a minimum load of 10mA to ensure proper regulation.
