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.

For VIN 2.5V and VIN = VOUT +1V. For VIN < 2.5V, the PSRR performance may be reduced.

AP7361C-33SPR 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.
