LT1028CN8 datasheet by Linear Technology

LT1028CN8 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LT1028CN8?
  The maximum power dissipation of the LT1028CN8 is 1.4W, which is limited by the package thermal resistance and the maximum junction temperature of 150°C.
• How do I ensure stability when using the LT1028CN8?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF, and to avoid using capacitors with high ESR (Equivalent Series Resistance). Additionally, the input and output pins should be decoupled with 0.1uF capacitors to reduce noise and oscillations.
• What is the recommended input voltage range for the LT1028CN8?
  The recommended input voltage range for the LT1028CN8 is 4.5V to 36V, although the device can operate up to 40V. However, operating the device at higher voltages may reduce its reliability and lifespan.
• Can I use the LT1028CN8 in a high-temperature environment?
  The LT1028CN8 is rated for operation up to 125°C, but its performance may degrade at higher temperatures. It is recommended to derate the device's power dissipation and output current at higher temperatures to ensure reliable operation.
• How do I protect the LT1028CN8 from overvoltage and overcurrent?
  The LT1028CN8 has built-in overcurrent protection, but it is still recommended to add external protection circuitry, such as a fuse or a current-limiting resistor, to prevent damage from overvoltage and overcurrent conditions.
