TPS2100DBVR datasheet by Texas Instruments

TPS2100DBVR Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the output of the TPS2100DBVR?
  The maximum current that can be drawn from the output of the TPS2100DBVR is 1A. However, it's recommended to limit the output current to 0.5A for optimal performance and to prevent overheating.
• How do I ensure that the TPS2100DBVR is properly powered on and off?
  To ensure proper power-on and power-off sequencing, connect the EN pin to a logic signal that is high during normal operation and low during shutdown. Additionally, make sure to follow the recommended power-up and power-down timing sequences outlined in the datasheet.
• What is the purpose of the PG pin, and how should it be connected?
  The PG (Power Good) pin is an open-drain output that indicates when the output voltage is within regulation. It can be connected to a microcontroller or other logic circuit to monitor the power supply status. Connect a pull-up resistor (typically 1kΩ to 10kΩ) to a voltage rail (e.g., VCC) to enable the PG pin.
• Can I use the TPS2100DBVR with an input voltage higher than 5.5V?
  No, the TPS2100DBVR is not designed to operate with input voltages higher than 5.5V. Exceeding the maximum input voltage can cause damage to the device. If you need to use a higher input voltage, consider using a voltage regulator or a different device that is rated for the desired input voltage range.
• How do I calculate the output voltage of the TPS2100DBVR?
  The output voltage of the TPS2100DBVR is adjustable using an external resistor divider network. Use the formula: VOUT = 1.22V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network. Choose R1 and R2 to achieve the desired output voltage within the range of 1.22V to 5.5V.
