L4995AJ datasheet by STMicroelectronics

L4995AJ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4995AJ?
  The maximum input voltage that can be applied to the L4995AJ is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L4995AJ is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the L4995AJ to operate?
  The minimum input voltage required for the L4995AJ to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the L4995AJ in a high-temperature environment?
  The L4995AJ is rated for operation up to 150°C, but it's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet to ensure reliable operation.
• How do I calculate the output voltage of the L4995AJ?
  The output voltage of the L4995AJ can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors in the feedback network, VIN is the input voltage, and VREF is the internal reference voltage (2.5V).
