MAX619ESA+ datasheet by Maxim Integrated Products

MAX619ESA+ Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX619ESA+?
  The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
• How do I ensure the MAX619ESA+ is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 22nF capacitor between the COMP and GND pins.
• What is the maximum output current I can draw from the MAX619ESA+?
  The maximum output current is 150mA, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
• Can I use the MAX619ESA+ in a high-temperature environment?
  The MAX619ESA+ is rated for operation up to 125°C, but the output current and voltage regulation may degrade at high temperatures. Ensure proper thermal design and derating to ensure reliable operation.
• How do I adjust the output voltage of the MAX619ESA+?
  The output voltage can be adjusted by connecting a resistor divider network between the VOUT and ADJ pins. The recommended resistor values are R1 = 1kΩ and R2 = 2.2kΩ for a 5V output.
