LP3853ES-3.3 datasheet by Texas Instruments

LP3853ES-3.3 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3853ES-3.3?
  The maximum input voltage that can be applied to the LP3853ES-3.3 is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure the LP3853ES-3.3 is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the inductance in the output circuit.
• What is the minimum input voltage required for the LP3853ES-3.3 to regulate the output voltage?
  The minimum input voltage required for the LP3853ES-3.3 to regulate the output voltage is around 3.5V, but it's recommended to keep it above 4V for reliable operation.
• Can I use the LP3853ES-3.3 in a high-temperature environment?
  The LP3853ES-3.3 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 reliable operation.
• How do I calculate the power dissipation of the LP3853ES-3.3?
  The power dissipation of the LP3853ES-3.3 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.
