LT1936IMS8E datasheet by Linear Technology

LT1936IMS8E Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1936IMS8E?
  The maximum input voltage that can be applied to the LT1936IMS8E is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• How do I ensure the LT1936IMS8E is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out high-frequency noise.
• Can I use the LT1936IMS8E in a high-temperature environment?
  The LT1936IMS8E is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curves provided in the datasheet.
• How do I calculate the output voltage ripple of the LT1936IMS8E?
  The output voltage ripple can be estimated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. A lower ESL and higher Cout will result in lower output voltage ripple.
• Can I use the LT1936IMS8E in a battery-powered application?
  Yes, the LT1936IMS8E is suitable for battery-powered applications due to its low quiescent current (IQ) and high efficiency. However, make sure to consider the battery's voltage range and the regulator's dropout voltage when selecting the input voltage and output voltage.
