AP2191FMG-7 datasheet by Diodes Incorporated

AP2191FMG-7 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the AP2191FMG-7 can handle?
  The AP2191FMG-7 can handle a maximum input voltage of 25V, but it's recommended to operate within the specified input voltage range of 7V to 18V for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use the recommended output capacitor value and type, as specified in the datasheet. Additionally, the input capacitor should be placed close to the VIN pin to minimize noise and ensure stable operation.
• What is the maximum output current that the AP2191FMG-7 can provide?
  The AP2191FMG-7 can provide a maximum output current of 1.5A, but it's recommended to operate within the specified output current range of 0.1A to 1.2A for optimal performance and to prevent overheating.
• How do I adjust the output voltage?
  The output voltage of the AP2191FMG-7 can be adjusted by using an external resistor divider network connected to the FB pin. The output voltage can be calculated using the formula provided in the datasheet.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
