TPS2013ADRG4 datasheet by Texas Instruments

TPS2013ADRG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS2013ADRG4?
  Texas Instruments recommends a compact layout with the input and output capacitors placed close to the device, and the input and output pins should be routed away from each other to minimize noise coupling. A 4-layer PCB with a solid ground plane is recommended.
• How do I ensure the TPS2013ADRG4 is stable and doesn't oscillate?
  To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor's ESR is less than 1 ohm. Additionally, place a 10nF to 100nF capacitor between the VIN and EN pins to filter noise and prevent oscillation.
• What is the maximum input voltage that can be applied to the TPS2013ADRG4?
  Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
• Can I use the TPS2013ADRG4 in a high-temperature environment?
  The TPS2013ADRG4 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the device's output current and voltage at elevated temperatures.
• How do I calculate the output voltage of the TPS2013ADRG4?
  The output voltage of the TPS2013ADRG4 is set by the resistive divider network connected to the FB pin. Use the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
