LP3883ES-1.2 datasheet by Texas Instruments

LP3883ES-1.2 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3883ES-1.2?
  The maximum input voltage that can be applied to the LP3883ES-1.2 is 15V. Exceeding this voltage may damage the device.
• How do I ensure stability of the output voltage in my design?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF with an ESR of 0.05Ω to 5Ω, and to place the capacitor close to the output pin of the regulator.
• What is the minimum input capacitance required for the LP3883ES-1.2?
  A minimum input capacitance of 1uF is recommended to ensure stability and to filter out noise on the input voltage.
• Can I use the LP3883ES-1.2 in a high-temperature environment?
  The LP3883ES-1.2 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 LP3883ES-1.2?
  The power dissipation of the LP3883ES-1.2 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.
