LT1054IDWR datasheet by Texas Instruments

LT1054IDWR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1054IDWR?
  The maximum input voltage that can be applied to the LT1054IDWR is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the LT1054IDWR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a minimum output capacitance of 10uF, and add a 10nF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the LT1054IDWR to operate?
  The minimum input voltage required for the LT1054IDWR to operate is 3.5V, but it's recommended to keep it above 4V for reliable operation.
• Can I use the LT1054IDWR in a high-temperature environment?
  The LT1054IDWR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LT1054IDWR?
  The output voltage of the LT1054IDWR can be calculated using the formula: Vout = (R1 / R2) * (VIN - Vref), where R1 and R2 are the resistors in the feedback network, VIN is the input voltage, and Vref is the internal reference voltage (2.5V).
