TPS77533DR datasheet by Texas Instruments

TPS77533DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS77533DR can handle?
  The TPS77533DR can handle input voltages up to 15V, but it's recommended to keep the input voltage below 13.2V for optimal performance and to prevent damage to the device.
• How do I ensure stability of the output voltage?
  To ensure stability of the output voltage, it's essential to use a capacitor with a low equivalent series resistance (ESR) and a high capacitance value (e.g., 10uF or higher) at the output. Additionally, the input capacitor should be placed close to the VIN pin to reduce noise and improve stability.
• What is the minimum input voltage required for the TPS77533DR to operate?
  The TPS77533DR can operate with input voltages as low as 2.7V, but the output voltage regulation may not be guaranteed below 3.3V input voltage.
• Can I use the TPS77533DR in a high-temperature environment?
  The TPS77533DR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's essential to ensure proper thermal management and consider the device's thermal characteristics when designing for high-temperature applications.
• How do I calculate the output voltage of the TPS77533DR?
  The output voltage of the TPS77533DR can be calculated using the following formula: VOUT = 1.5V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network. The output voltage range is from 1.5V to 5.5V.
