AP7365
Application Information (continued)
Adjustable Operation
The AP7365 provides output voltage from 0.8V to 5.0V through external resistor divider as shown below.

R1

VOUT

The output voltage is calculated by:
VOUT
VREF1
R1
R2
Where VREF = 0.8V (the internal reference voltage)
Rearranging the equation will give the following that is used for adjusting the output to a particular voltage:
R1
R2
VOUT
VREF

To maintain the stability of the internal reference voltage, R2 needs to be kept smaller than 80kΩ.
No Load Stability
Other than external resistor divider, no minimum load is required to keep the device stable. The device will remain stable and regulated in no load
condition.
ON/OFF Input Operation
The AP7365 is turned on by setting the EN pin high, and is turned off by pulling it low. If this feature is not used, the EN pin should be tied to IN pin
to keep the regulator output on at all time. To ensure proper operation, the signal source used to drive the EN pin must be able to swing above
and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section under VIL and VIH.
Current Limit Protection
When output current at OUT pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to
approximately 1.4A to prevent overcurrent and to protect the regulator from damage due to overheating.
Short Circuit Protection
When OUT pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 240mA. This feature
protects the regulator from overcurrent and damage due to overheating.
Thermal Shutdown Protection
Thermal protection disables the output when the junction temperature rises to approximately +145°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.
Ultra Fast Start-Up
After enabled, the AP7365 is able to provide full power in as little as hundreds of microseconds, typically 200µs, without sacrificing low ground
current. This feature will help load circuitry move in and out of standby mode in real time, eventually extend battery life for mobile phones and
other portable devices.
