TLV2264AMJB datasheet by Texas Instruments

TLV2264AMJB Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TLV2264AMJB?
  Texas Instruments recommends a compact layout with the TLV2264AMJB placed close to the power supply pins, with short traces and minimal inductance to reduce noise and ensure stability. A 4-layer PCB with a solid ground plane is recommended.
• How do I ensure the TLV2264AMJB is stable and doesn't oscillate?
  To ensure stability, use a minimum of 10nF ceramic capacitor between the VCC and GND pins, and a 1uF capacitor between the VCC and VIN pins. Also, ensure that the input and output capacitors are placed close to the device and have low ESR.
• What is the maximum input voltage that the TLV2264AMJB can handle?
  The TLV2264AMJB can handle a maximum input voltage of 15V, but it's recommended to operate within the specified range of 4.5V to 12V for optimal performance and reliability.
• Can I use the TLV2264AMJB in a high-temperature environment?
  The TLV2264AMJB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as temperature increases to ensure reliability and prevent thermal shutdown.
• How do I calculate the output voltage of the TLV2264AMJB?
  The output voltage of the TLV2264AMJB can be calculated using the formula: VOUT = (1 + R1/R2) * VREF, where R1 and R2 are the resistors connected to the FB pin, and VREF is the internal reference voltage (1.25V).
