LP2901DR datasheet by Texas Instruments

LP2901DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LP2901DR can handle?
  The LP2901DR can handle input voltages up to 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
• How do I ensure the LP2901DR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize parasitic inductance.
• What is the minimum input voltage required for the LP2901DR to operate?
  The LP2901DR can operate with input voltages as low as 7V, but the output voltage regulation may not be as accurate. For optimal performance, it's recommended to use an input voltage of at least 9V.
• Can I use the LP2901DR in a high-temperature environment?
  The LP2901DR is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink and ensure good airflow to keep the device temperature below 100°C for optimal performance and reliability.
• How do I calculate the output voltage of the LP2901DR?
  The output voltage of the LP2901DR can be calculated using the formula: Vout = (1 + R2/R1) * 1.24V, where R1 and R2 are the resistors used in the feedback network.
