LP3982IMM-ADJ Frequently Asked Questions (FAQs)

  • The minimum input voltage required is 2.5V, but it's recommended to have at least 1V of headroom above the desired output voltage to ensure proper regulation.
  • The output voltage can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula provided in the datasheet.
  • The maximum output current is 1.5A, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
  • To ensure stability, it's recommended to use a minimum output capacitance of 10uF with an ESR of 0.1Ω or less, and to place the capacitor close to the output pin. Additionally, a 1uF capacitor on the input pin can help to filter out noise and prevent oscillations.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific device and operating conditions. The device will automatically shut down when the junction temperature exceeds this threshold to prevent damage.
