R1172N331D-TR-FE Frequently Asked Questions (FAQs)

  • The thermal resistance (θJA) of the R1172N331D-TR-FE is typically around 60°C/W, which means it can dissipate heat efficiently.
  • While the R1172N331D-TR-FE has an operating temperature range of -40°C to 105°C, it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent overheating.
  • To ensure stability, use a minimum output capacitance of 1μF, and consider adding a 10nF to 100nF ceramic capacitor in parallel with the output capacitor to prevent oscillation.
  • A 1μF to 10μF input capacitor is recommended to filter out noise and ensure stable operation. The capacitor should have a voltage rating of at least 6.3V.
  • Yes, the R1172N331D-TR-FE is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5μA and low dropout voltage (VDO) of 0.23V.
