ST1PS01AJR Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the package is recommended for optimal thermal performance. The thermal vias should be connected to the ground plane to dissipate heat efficiently.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less. Additionally, the output voltage should be decoupled with a 10nF ceramic capacitor.
  • The maximum input voltage that can be applied to the device is 28V. Exceeding this voltage may damage the device.
  • The device has a built-in overcurrent protection (OCP) feature that limits the output current to 2.5A. However, it is recommended to add an external fuse or PTC thermistor to protect the device from overcurrent conditions.
  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close as possible to the VIN pin.
