TPS2087D datasheet by Texas Instruments

TPS2087D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS2087D can handle?
  The TPS2087D can handle input voltages up to 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation.
• How do I choose the right output capacitor for the TPS2087D?
  The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a value between 1uF to 10uF, and a voltage rating of at least 1.5 times the output voltage.
• What is the minimum input capacitance required for the TPS2087D?
  The minimum input capacitance required for the TPS2087D is 1uF, but it's recommended to use a higher value (e.g. 4.7uF) to ensure stable operation.
• Can I use the TPS2087D in a high-temperature environment?
  The TPS2087D is rated for operation up to 85°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
• How do I ensure the TPS2087D is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitance, and avoid using long traces or wires that can cause oscillations.
