The LT1083CP can handle input voltages up to 30V, but it's recommended to keep the input voltage at least 2V above the output voltage to ensure proper regulation.
To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.05 ohms or less, and keep the input capacitance to a minimum (less than 1uF).
The dropout voltage of the LT1083CP is typically around 1.5V, which means the input voltage must be at least 1.5V above the output voltage to maintain regulation.
The LT1083CP is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to derate the output current and consider using a heat sink if operating in a high-temperature environment.
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the LT1083CP from voltage surges or spikes. You can also add a series resistor and capacitor to filter out high-frequency noise.
