L2293Q Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the L2293Q to minimize EMI?
  A good PCB layout for the L2293Q involves keeping the input and output stages separate, using a star-ground configuration, and placing the device close to the power source. Additionally, using a 4-layer PCB with a dedicated ground plane can help reduce EMI.
• How do I ensure the L2293Q is properly thermally managed?
  To ensure proper thermal management, make sure to provide a sufficient heat sink, use thermal interface material (TIM) to fill gaps, and ensure good airflow around the device. The maximum junction temperature (Tj) should not exceed 150°C.
• What is the recommended input capacitor value and type for the L2293Q?
  The recommended input capacitor value is 10uF to 22uF, with a low ESR (Equivalent Series Resistance) and a voltage rating of at least 25V. A ceramic or film capacitor is recommended, such as an X7R or X5R type.
• How do I protect the L2293Q from overvoltage and undervoltage conditions?
  Use a voltage supervisor or a voltage monitor IC to detect overvoltage and undervoltage conditions. You can also add a voltage clamp or a TVS (Transient Voltage Suppressor) diode to protect the device from voltage spikes.
• What is the recommended output capacitor value and type for the L2293Q?
  The recommended output capacitor value is 10uF to 47uF, with a low ESR and a voltage rating of at least 10V. A ceramic or film capacitor is recommended, such as an X7R or X5R type.
