TPS2087DR datasheet by Texas Instruments

TPS2087DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2087DR?
  The maximum input voltage that can be applied to the TPS2087DR is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can damage the device.
• How do I ensure that the TPS2087DR is properly powered up and configured?
  To ensure proper power-up and configuration, follow the recommended power-up sequence and configuration guidelines outlined in the datasheet, including setting the EN pin high, configuring the ILIM pin, and ensuring proper output capacitor selection.
• What is the minimum output capacitance required for stable operation?
  The minimum output capacitance required for stable operation is 10uF, as specified in the datasheet. However, it's recommended to use a higher value capacitor (e.g., 22uF) to ensure stable operation and minimize output voltage ripple.
• Can I use the TPS2087DR in a high-temperature environment?
  The TPS2087DR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's essential to consider the device's thermal characteristics and ensure proper thermal management in high-temperature applications.
• How do I calculate the current limit threshold of the TPS2087DR?
  The current limit threshold can be calculated using the formula: I_LIM = (V_ILIM / R_ILIM) x (R_S / R_ILIM), where V_ILIM is the voltage on the ILIM pin, R_ILIM is the resistance between the ILIM pin and GND, and R_S is the sense resistor value. Refer to the datasheet for more information.
