LD1084D2M-R datasheet by STMicroelectronics

LD1084D2M-R Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1084D2M-R?
  The maximum input voltage that can be applied to the LD1084D2M-R is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the LD1084D2M-R is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and decoupling capacitor values, and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the loop area of the input and output connections.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.05Ω, but it's recommended to use a capacitor with an ESR of 0.01Ω or lower for optimal performance.
• Can I use the LD1084D2M-R in a high-temperature environment?
  The LD1084D2M-R is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability. Consult the datasheet for specific derating guidelines.
• How do I calculate the power dissipation of the LD1084D2M-R?
  The power dissipation of the LD1084D2M-R can be calculated using the formula: Pd = (Vin - Vout) x Iout + Vin x Iq, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
