REG1117A-2.5 Frequently Asked Questions (FAQ)
-
The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
-
To ensure a stable output voltage, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum of 1uF input capacitor. Also, keep the input voltage at least 2V higher than the output voltage.
-
The minimum input voltage required is 3.5V, but it's recommended to keep it above 4V for optimal performance.
-
The REG1117A-2.5 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability.
-
Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Make sure to keep the power dissipation below the maximum rating of 1.5W.
