LM1086IT-3.3/NOPB datasheet by Texas Instruments

LM1086IT-3.3/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that I can apply to the LM1086IT-3.3/NOPB?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• Can I use the LM1086IT-3.3/NOPB in a high-temperature environment?
  The LM1086IT-3.3/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to prevent overheating and ensure reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and keep the input capacitance to a minimum (less than 1uF) to prevent oscillation.
• Can I use the LM1086IT-3.3/NOPB in a battery-powered device?
  Yes, the LM1086IT-3.3/NOPB is suitable for battery-powered devices, but be aware of the quiescent current (IQ) which is around 5mA, and consider using a low-dropout regulator or a switching regulator for better efficiency.
• How do I protect the LM1086IT-3.3/NOPB from input voltage transients?
  Use a TVS (transient voltage suppressor) diode or a voltage clamp at the input to protect the regulator from voltage transients and spikes.
