TPS60121PWP datasheet by Texas Instruments

TPS60121PWP Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value and type for the TPS60121PWP?
  A 1-10uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor (CIN) to ensure stability and low ESR.
• How do I optimize the output capacitor selection for the TPS60121PWP?
  Choose an output capacitor (COUT) with a low ESR (< 100mΩ) and a value between 1-22uF. A ceramic capacitor with an X5R or X7R dielectric is recommended. The output capacitor value should be selected based on the desired output voltage ripple and transient response.
• What is the maximum input voltage that the TPS60121PWP can handle?
  The TPS60121PWP can handle a maximum input voltage of 5.5V, but it's recommended to operate within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
• Can I use the TPS60121PWP in a high-temperature environment?
  The TPS60121PWP is rated for operation up to 85°C, but it's recommended to derate the output current and ensure proper thermal management to prevent overheating and ensure reliability.
• How do I ensure the TPS60121PWP is stable and doesn't oscillate?
  Ensure that the input and output capacitors are properly selected and placed close to the device. Also, make sure the PCB layout is designed to minimize parasitic inductance and capacitance. A stable voltage regulator requires a well-designed PCB layout and proper component selection.
