LM20123MH/NOPB datasheet by Texas Instruments

LM20123MH/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A good PCB layout for the LM20123MH/NOPB should include a solid ground plane, wide power traces, and a thermal relief pattern under the device to facilitate heat dissipation. TI provides a recommended PCB layout in the datasheet.
• How do I ensure stability in the output voltage?
  To ensure stability in the output voltage, it's essential to follow the recommended capacitor selection and placement guidelines in the datasheet. Additionally, the output capacitor's ESR (Equivalent Series Resistance) should be within the recommended range.
• What is the maximum input voltage that can be applied to the device?
  The maximum input voltage that can be applied to the LM20123MH/NOPB is 42V. Exceeding this voltage may cause damage to the device.
• Can I use the LM20123MH/NOPB in a high-temperature environment?
  The LM20123MH/NOPB is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and heat dissipation in high-temperature applications.
• How do I protect the device from overcurrent and short-circuit conditions?
  The LM20123MH/NOPB has built-in overcurrent protection, but it's still essential to add external protection components, such as fuses or current-limiting resistors, to prevent damage from excessive current or short-circuit conditions.
