LM285DRG4-1-2 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with the voltage reference at the center, and decoupling capacitors placed close to the device. A solid ground plane and short traces can also help reduce noise and improve performance.
  • To ensure stability, make sure to follow the recommended operating conditions, including a minimum load capacitance of 10nF and a maximum load capacitance of 100nF. Also, avoid using long traces or wires that can introduce inductance and cause oscillation.
  • The typical start-up time for the LM285DRG4-1-2 is around 10ms, but this can vary depending on the specific application and operating conditions. It's recommended to consult the datasheet and application notes for more information.
  • No, the LM285DRG4-1-2 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it's not intended to regulate voltage or provide a high current output.
  • The LM285DRG4-1-2 has a typical temperature coefficient of 10ppm/°C, which means that the output voltage can vary by up to 10ppm for every degree Celsius change in temperature. This can affect the accuracy of the voltage reference, especially in high-precision applications.
