L6902D Frequently Asked Questions (FAQs)

  • The L6902D can operate from -40°C to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • The L6902D requires a proper power-on sequence to ensure reliable operation. Apply VCC before VIN, and ensure VCC is stable before applying VIN.
  • The recommended input capacitor value is 10uF to 22uF, with an ESR of 0.1Ω to 1Ω, to ensure stability and reduce output voltage ripple.
  • Yes, the L6902D is suitable for high-reliability applications, as it is designed with built-in protection features such as overcurrent protection, undervoltage lockout, and thermal shutdown.
  • The output voltage of the L6902D can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.25V), and R1 and R2 are the feedback resistors.
