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 load current of 5mA. Also, keep the input voltage ripple low and use a low-ESR capacitor.
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 LM1086CSX-2.5/NOPB is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating and reduce the risk of thermal shutdown.
Use a voltage clamp or a transient voltage suppressor (TVS) diode at the input to protect the regulator from voltage surges or spikes. Additionally, consider adding a fuse or a current limiter to prevent overcurrent conditions.
