MAX800LCSE+ datasheet by Maxim Integrated Products

MAX800LCSE+ Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the MAX800LCSE+?
  The MAX800LCSE+ requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
• How do I handle the startup sequence for the MAX800LCSE+?
  The MAX800LCSE+ has a specific startup sequence that must be followed to ensure proper operation. The sequence is: VCC, EN, and then VIN. This sequence ensures that the internal regulators are enabled in the correct order and prevents damage to the device.
• What is the maximum input voltage that the MAX800LCSE+ can handle?
  The MAX800LCSE+ can handle input voltages up to 28V, but it is recommended to limit the input voltage to 24V to ensure reliable operation and to prevent damage to the device.
• How do I calculate the output voltage of the MAX800LCSE+?
  The output voltage of the MAX800LCSE+ can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors used to set the output voltage, VIN is the input voltage, and VREF is the internal reference voltage (1.25V).
• What is the purpose of the EN pin on the MAX800LCSE+?
  The EN (enable) pin on the MAX800LCSE+ is used to enable or disable the device. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and enters a low-power shutdown mode.
