LP38502SD-ADJ/NOPB datasheet by Texas Instruments

LP38502SD-ADJ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LP38502SD-ADJ/NOPB can handle?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I adjust the output voltage of the LP38502SD-ADJ/NOPB?
  The output voltage can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula provided in the datasheet.
• What is the minimum input voltage required for the LP38502SD-ADJ/NOPB to function properly?
  The minimum input voltage is 2.5V, but it's recommended to keep it above 3V for optimal performance and to ensure that the output voltage remains stable.
• Can I use the LP38502SD-ADJ/NOPB in a high-temperature environment?
  The LP38502SD-ADJ/NOPB is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C to ensure reliable operation and to prevent overheating.
• How do I ensure that the LP38502SD-ADJ/NOPB is stable and doesn't oscillate?
  To ensure stability, it's recommended to use a minimum output capacitance of 10uF and to keep the output capacitor's ESR (Equivalent Series Resistance) below 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR below 1 ohm.
