LT1158ISW datasheet by Linear Technology

LT1158ISW Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1158ISW can handle?
  The LT1158ISW can handle input voltages up to 36V, but it's recommended to keep the input voltage below 30V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 1.5V to 15V.
• What is the maximum output current that the LT1158ISW can provide?
  The LT1158ISW can provide up to 5A of output current, but it's recommended to keep the output current below 3A for optimal performance and reliability.
• How do I reduce the noise and ripple on the output voltage?
  To reduce noise and ripple, use a low-ESR output capacitor, and consider adding a noise-reducing capacitor (e.g. 10nF) between the output and ground. Also, keep the input voltage as clean as possible.
• Can I use the LT1158ISW in a high-temperature environment?
  The LT1158ISW is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability. Use a heat sink or thermal management system if necessary.
