LM78L15ACM datasheet by Texas Instruments

LM78L15ACM Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM78L15ACM?
  The maximum input voltage that can be applied to the LM78L15ACM is 35V, but it's recommended to keep it below 30V for reliable operation.
• Can I use the LM78L15ACM in a high-temperature environment?
  The LM78L15ACM is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
• How do I ensure the stability of the LM78L15ACM output voltage?
  To ensure stability, use a minimum output capacitance of 10uF, and keep the input capacitance as low as possible. Also, ensure that the input voltage is well-regulated and free of noise.
• Can I use the LM78L15ACM in a switching regulator application?
  No, the LM78L15ACM is a linear regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-power applications.
• What is the minimum input voltage required for the LM78L15ACM to regulate properly?
  The minimum input voltage required for the LM78L15ACM to regulate properly is 2.5V above the output voltage. For example, for a 15V output, the minimum input voltage should be at least 17.5V.
