L4995JTR datasheet by STMicroelectronics

L4995JTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L4995JTR can handle?
  The L4995JTR can handle an input voltage up to 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I ensure the L4995JTR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a compensation network (R1, R2, C1) as shown in the datasheet.
• What is the minimum input voltage required for the L4995JTR to operate?
  The L4995JTR can operate with an input voltage as low as 6.5V, but the output voltage regulation may not be guaranteed below 7V.
• Can I use the L4995JTR in a high-temperature environment?
  The L4995JTR is rated for operation up to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
• How do I calculate the output voltage of the L4995JTR?
  The output voltage (Vout) can be calculated using the formula: Vout = (R2 / R1) * (1.25V), where R1 and R2 are the resistors in the feedback network.
