LM317LZ-AP Frequently Asked Questions (FAQ)

  • The minimum input voltage required for the LM317LZ-AP to function properly is 3V above the output voltage. For example, if the output voltage is set to 5V, the minimum input voltage should be at least 8V.

  • To ensure stability and prevent oscillations, a minimum output capacitance of 1uF is recommended. Additionally, the input capacitor should be at least 10uF to filter out noise and ripple.

  • The maximum current that the LM317LZ-AP can deliver is 1.5A. However, it's recommended to derate the current to 1A or less to ensure reliable operation and prevent overheating.

  • The output voltage of the LM317LZ-AP can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V).

  • The thermal shutdown temperature of the LM317LZ-AP is typically around 150°C. When the junction temperature exceeds this value, the regulator will shut down to prevent damage.
