REG1117A/2K5 Frequently Asked Questions (FAQ)
-
The maximum input voltage for the REG1117A/2K5 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
-
To ensure a stable and accurate 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 maximum output current for the REG1117A/2K5 is 1.5A, but it's recommended to keep it below 1A for optimal performance and to prevent overheating.
-
To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
-
The thermal shutdown temperature for the REG1117A/2K5 is around 150°C. If the junction temperature exceeds this value, the regulator will shut down to prevent damage.
