The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be between 0.3 ohms and 10 ohms.
The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
The LD1117ADT18TR is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.
Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
