LM185BYH1.2-SMD datasheet by Texas Instruments

LM185BYH1.2-SMD Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LM185BYH1.2-SMD to ensure optimal performance?
  Texas Instruments recommends a star-grounded layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize noise and parasitic inductance.
• How do I handle the thermal considerations for the LM185BYH1.2-SMD?
  The LM185BYH1.2-SMD has a thermal pad that must be connected to a copper plane on the PCB to dissipate heat. Ensure good thermal conductivity by using a thermal via or a copper pour under the device.
• What is the recommended input bypass capacitor value for the LM185BYH1.2-SMD?
  A 10nF to 100nF ceramic capacitor is recommended to be placed as close as possible to the input pin to filter out high-frequency noise and ensure stability.
• Can I use the LM185BYH1.2-SMD as a voltage regulator?
  No, the LM185BYH1.2-SMD is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage like a linear voltage regulator.
• How do I ensure the accuracy of the LM185BYH1.2-SMD over temperature?
  The LM185BYH1.2-SMD has a specified temperature coefficient of 10ppm/°C. To ensure accuracy, use a thermally stable PCB design, and consider using a temperature compensation circuit or a more accurate voltage reference if required.
