UMD25NTR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for UMD25NTR?
  The recommended operating voltage range for UMD25NTR is 2.5V to 5.5V, although the absolute maximum rating is 6.5V.
• How do I ensure the stability of the output voltage in UMD25NTR?
  To ensure the stability of the output voltage, it is recommended to use a 10uF or larger ceramic capacitor for CIN and a 10uF or larger ceramic capacitor for COUT, and to place them as close to the IC as possible.
• What is the maximum output current of UMD25NTR?
  The maximum output current of UMD25NTR is 500mA, although it can be increased to 1A with an external transistor.
• How do I reduce the noise and ripple in the output voltage of UMD25NTR?
  To reduce the noise and ripple in the output voltage, it is recommended to use a noise filter capacitor (e.g. 10nF) between the VIN and GND pins, and to use a low-ESR capacitor for COUT.
• What is the thermal resistance of UMD25NTR?
  The thermal resistance of UMD25NTR is 125°C/W (junction to ambient) and 45°C/W (junction to case).
