    4. Conditions:

    ️· Most electrical characteristics are measured at:
    - V<sub>IN</sub> = 1.5V
    - V<sub>OUT</sub> = 1.0V
    - V<sub>BIAS</sub> = 10V
    - T<sub>J</sub> = -40°C to +125°C (Junction Temperature)
    - C<sub>IN</sub> = 22μF (Input Capacitor)
    - C<sub>OUT</sub> = 22μF (Output Capacitor)
    - C<sub>BYP</sub> = 1nF (Bypass Capacitor)

    Important Notes:

    ️· This is an *excerpt*. The full datasheet would contain more detailed information and graphs.
    ️· The dropout voltage is highly dependent on the output voltage (V<sub>OUT</sub>) and bias voltage (V<sub>BIAS</sub>). The provided values are illustrative.
    ️· The conditions listed are for the specific measurements in the table. The device may operate outside these parameters, but characteristics are not guaranteed.
