LM1117T-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The minimum input voltage required is 3V, but it's recommended to have at least 1.5V 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 adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.25V * (1 + R1/R2).
  • The maximum output current of the LM1117T-ADJ/NOPB is 1A, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, the input capacitor should be at least 10uF with an ESR of less than 5 ohms.
  • The thermal shutdown temperature of the LM1117T-ADJ/NOPB is typically around 150°C, but it can vary depending on the specific device and operating conditions.
