The recommended operating voltage range for the TLE2027CD is 4.5V to 16V, although it can operate up to 18V with reduced performance.
To ensure proper biasing, connect the midpoint of the input voltage range to the VCC/2 pin, and decouple the VCC pin with a 0.1uF capacitor to ground.
The maximum input voltage that can be applied to the TLE2027CD without damaging the device is 22V, although operation above 18V is not recommended.
No, the TLE2027CD is not designed to be used as a voltage regulator. It is a high-speed, low-power operational amplifier intended for signal amplification and conditioning.
To minimize noise and oscillations, use proper PCB layout techniques, decouple the power supply with capacitors, and add resistors and capacitors to the input and output stages as necessary to filter out high-frequency noise.
