LM193FK Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the LM193FK is -40°C to 125°C, although it can function up to 150°C with reduced performance.

  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be located close to the regulator. Additionally, a 1uF to 10uF input capacitor can be used to improve transient response.

  • The maximum input voltage that the LM193FK can handle is 30V, although it's recommended to keep the input voltage at least 2V above the desired output voltage to ensure proper regulation.

  • The LM193FK is designed for low-current applications, with a maximum output current of 1A. For high-current applications, consider using a different voltage regulator or adding an external pass transistor to increase the current capability.

  • The LM193FK has built-in overvoltage protection, but it's still recommended to add external protection circuitry, such as a voltage supervisor or a crowbar circuit, to protect against overvoltage and undervoltage conditions.
