LT3021EDH-1.8#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT3021EDH-1.8?
  The maximum input voltage that can be applied to the LT3021EDH-1.8 is 36V. Exceeding this voltage can cause damage to the device.
• How do I ensure stability in the LT3021EDH-1.8 output voltage?
  To ensure stability in the LT3021EDH-1.8 output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitance should be at least 1uF.
• What is the typical dropout voltage of the LT3021EDH-1.8?
  The typical dropout voltage of the LT3021EDH-1.8 is 300mV at an output current of 1A. This means that the input voltage must be at least 300mV higher than the output voltage to maintain regulation.
• Can I use the LT3021EDH-1.8 in a high-temperature environment?
  The LT3021EDH-1.8 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and input voltage at high temperatures.
• How do I calculate the power dissipation of the LT3021EDH-1.8?
  The power dissipation of the LT3021EDH-1.8 can be calculated using the formula: Pd = (Vin - Vout) x Iout. Where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
