REG103UA-2.5 Frequently Asked Questions (FAQ)
-
The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
-
The output voltage is fixed at 2.5V and does not require any external resistors or adjustments. However, it's essential to ensure the input voltage is within the recommended range and the device is properly decoupled.
-
The minimum input voltage is 3.2V, but it's recommended to keep it above 3.5V for optimal performance and to ensure the output voltage remains stable.
-
The REG103UA-2.5 has a maximum operating temperature of 125°C. However, it's essential to ensure proper heat sinking and thermal management to prevent overheating, especially in high-temperature environments.
-
Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Ensure to consider the maximum input voltage, output current, and thermal resistance when calculating power dissipation.
