Notes:
7. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value. This parameter only applies to output voltages above 1.2V since minimum VIN = 2.2V. 8. For VIN ≥ 2.5V and VIN = VOUT +1V. For VIN < 2.5V, the PSRR performance may be reduced.

- Notes: 4. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.

Recommended Operating Conditions
| Symbol | Parameter | Min | Max | Unit |
|---|---|---|---|---|
| VIN | Input Voltage | 2.2 | 6.0 | V |
| VOUT | Output Voltage | 0.8 | 5.0 | V |
| IOUT | Output Current (Note 6) | 1.0 | A | |
| TA | Operating Ambient Temperature | -40 | +85 | C |
Note: 6. The device maintains a stable, regulated output voltage without a load current. When the output current is large, attention should be given to the limitation of the package power dissipation.
Thermal Information
Thermal protection disables the output when the junction temperature rises to approximately +150°C, allowing the device to cool down. When the junction temperature reduces to approximately +130°C the output circuitry is enabled again. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the heat dissipation of the regulator, protecting it from damage due to overheating.
