LT3090HMSE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT3090?
  The maximum input voltage that can be applied to the LT3090 is 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I ensure the LT3090 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• Can I use the LT3090 in a high-temperature environment?
  Yes, the LT3090 is rated for operation up to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C. Make sure to follow the thermal management guidelines in the datasheet to ensure reliable operation.
• How do I calculate the output voltage of the LT3090?
  The output voltage of the LT3090 can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.2V), R1 is the feedback resistor, and R2 is the divider resistor.
• What is the minimum load current required for the LT3090 to maintain regulation?
  The LT3090 can maintain regulation down to a minimum load current of 1mA, but it's recommended to have a minimum load current of 10mA for optimal performance.
