LD39150PU33R Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 2-layer or 4-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
  • To ensure reliable startup and shutdown, add a 1-2uF capacitor between the EN pin and GND, and a 10kΩ resistor between the EN pin and VIN. This helps to filter noise and prevent unwanted shutdowns.
  • Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent overheating.
  • The output voltage tolerance is typically ±2% over the entire operating temperature range. To calculate the output voltage accuracy, use the formula: Vout = Vref x (1 + (R1/R2)), where Vref is the internal reference voltage (1.25V) and R1 and R2 are the feedback resistors.
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling, placed as close to the VIN pin as possible. This helps to filter input noise and prevent oscillations.
