LP3853ES-1.8 datasheet by Texas Instruments

LP3853ES-1.8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3853ES-1.8?
  The maximum input voltage that can be applied to the LP3853ES-1.8 is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure the LP3853ES-1.8 is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
• What is the minimum input voltage required for the LP3853ES-1.8 to operate?
  The minimum input voltage required for the LP3853ES-1.8 to operate is 2.5V, but it's recommended to keep it above 2.7V for reliable operation.
• Can I use the LP3853ES-1.8 in a high-temperature environment?
  The LP3853ES-1.8 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I calculate the power dissipation of the LP3853ES-1.8?
  The power dissipation of the LP3853ES-1.8 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.
