LMS1587IS-ADJ Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 6.3V. This capacitor helps to filter out noise and ripple on the input voltage.
  • The output voltage of the LMS1587IS-ADJ can be adjusted by connecting a resistor divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.25V x (1 + R1/R2).
  • The maximum output current of the LMS1587IS-ADJ is 3A. However, the output current should be derated based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
  • The LMS1587IS-ADJ has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be added using external components such as zener diodes or voltage supervisors to protect the device from voltage transients and faults.
  • The thermal shutdown temperature of the LMS1587IS-ADJ is typically around 150°C to 160°C. When the device temperature exceeds this threshold, it will shut down to prevent damage from overheating.
