L4995RJTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L4995RJTR can handle?
  The L4995RJTR can handle input voltages up to 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I ensure the L4995RJTR 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 10nF capacitor between the VIN and EN pins.
• What is the minimum input voltage required for the L4995RJTR to operate?
  The L4995RJTR can operate with input voltages as low as 6.5V, but the output voltage regulation may not be guaranteed below 7V.
• Can I use the L4995RJTR in a high-temperature environment?
  The L4995RJTR is rated for operation up to 150°C, but the maximum junction temperature should not exceed 125°C for reliable operation.
• How do I calculate the output voltage of the L4995RJTR?
  The output voltage 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 (1.25V).
