L4925PD datasheet by STMicroelectronics

L4925PD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L4925PD can handle?
  The L4925PD can handle a maximum input voltage of 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure the L4925PD 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 as described in the datasheet.
• What is the minimum input voltage required for the L4925PD to operate?
  The L4925PD can operate with an input voltage as low as 7V, but the output voltage regulation may not be guaranteed below 8V.
• Can I use the L4925PD in a high-temperature environment?
  The L4925PD is rated for operation up to 150°C, but the maximum junction temperature should not exceed 125°C for reliable operation. Ensure proper thermal management and heat sinking to prevent overheating.
• How do I calculate the output voltage of the L4925PD?
  The output voltage of the L4925PD can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (2.5V), and R1 and R2 are the resistors in the feedback network.
