TPS77501D datasheet by Texas Instruments

TPS77501D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS77501D can handle?
  The TPS77501D can handle input voltages up to 17V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
• How do I choose the right output capacitor for the TPS77501D?
  The output capacitor should have a minimum value of 10uF, and a maximum ESR of 1 ohm. A ceramic or tantalum capacitor with a voltage rating of 6.3V or higher is recommended.
• Can I use the TPS77501D in a high-temperature environment?
  The TPS77501D is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability. Thermal design and heat sinking may be necessary for high-temperature applications.
• How do I ensure the TPS77501D is stable and doesn't oscillate?
  To ensure stability, use a minimum output capacitance of 10uF, and keep the output capacitor's ESR below 1 ohm. Also, avoid using long, thin traces for the output capacitor, and keep the input and output capacitors close to the device.
• Can I use the TPS77501D in a battery-powered device?
  Yes, the TPS77501D is suitable for battery-powered devices due to its low quiescent current (IQ) of 30uA. However, consider using a low-dropout regulator (LDO) with a lower IQ if the device will be in sleep mode for extended periods.
