LP3882ES-1.2/NOPB datasheet by Texas Instruments

LP3882ES-1.2/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3882ES-1.2/NOPB?
  The maximum input voltage that can be applied to the LP3882ES-1.2/NOPB is 15V. Exceeding this voltage may damage the device.
• How do I ensure stability of the output voltage in my design?
  To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 0.1 ohms or less, and to place the capacitor as close to the output pin as possible.
• What is the minimum input capacitance required for the LP3882ES-1.2/NOPB?
  The minimum input capacitance required for the LP3882ES-1.2/NOPB is 1uF. However, it is recommended to use a higher capacitance value, such as 4.7uF or 10uF, to ensure stability and reduce noise.
• Can I use the LP3882ES-1.2/NOPB in a high-temperature environment?
  The LP3882ES-1.2/NOPB 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 voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LP3882ES-1.2/NOPB?
  The output voltage of the LP3882ES-1.2/NOPB can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
