TPS2511DGN datasheet by Texas Instruments

TPS2511DGN Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS2511DGN can handle?
  The TPS2511DGN 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 ensure the TPS2511DGN is properly powered up and configured?
  To ensure proper power-up and configuration, follow the recommended power-up sequence: VCC, then EN, then IN. Also, make sure to tie the EN pin high to enable the device, and configure the IN pin according to the desired output voltage.
• What is the minimum input capacitance required for stable operation?
  The TPS2511DGN requires a minimum input capacitance of 1uF to ensure stable operation. However, it's recommended to use a 2.2uF or larger capacitor to ensure optimal performance.
• Can I use the TPS2511DGN in a high-temperature environment?
  The TPS2511DGN 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. Consult the datasheet for specific derating guidelines.
• How do I calculate the output voltage of the TPS2511DGN?
  The output voltage of the TPS2511DGN can be calculated using the following formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.2V).
