MAX873AESA+ datasheet by Maxim Integrated Products

MAX873AESA+ Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX873AESA+?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input ripple and improve transient response.
• How do I ensure stability of the MAX873AESA+ regulator?
  To ensure stability, it is recommended to use a minimum output capacitor of 10uF with an ESR of 1 ohm or less. Additionally, the input capacitor should be placed close to the VIN pin, and the output capacitor should be placed close to the VOUT pin.
• What is the maximum input voltage that the MAX873AESA+ can handle?
  The MAX873AESA+ can handle a maximum input voltage of 5.5V. Exceeding this voltage may cause damage to the device.
• Can I use the MAX873AESA+ in a high-temperature environment?
  The MAX873AESA+ is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and input voltage at high temperatures.
• How do I calculate the output voltage of the MAX873AESA+?
  The output voltage of the MAX873AESA+ can be calculated using the following formula: VOUT = (R1 / R2) x 0.6V, where R1 and R2 are the resistors connected to the FB pin.
