The characteristics of low dropout voltage and low quiescent current

make it suitable for low power applications such as battery powered

devices. The typical quiescent current is approximately 60μA. Built-in

current-limit and thermal-shutdown functions prevent IC from damage

in fault conditions.

Notes:

5. 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 input voltages above minimum V_IN= 2.0V.

6. At V_IN< 2.3V, the PSRR performance may be reduced.

Typical Performance Characteristics (continued)

Application Information

Input Capacitor

A 1μF ceramic capacitor is recommended between IN and GND pins to decouple input power supply glitch and noise. The amount of the

capacitance may be increased without limit. This input capacitor must be located as close as possible to the device to assure input stability and

reduce noise. For PCB layout, a wide copper trace is required for both IN and GND pins. A lower ESR capacitor type allows the use of less

capacitance, while higher ESR type requires more capacitance.

Output Capacitor

The output capacitor is required to stabilize and improve the transient response of the LDO. The AP7366 is stable with very small ceramic output

capacitors. Using a ceramic capacitor value that is at least 2.2μF with 10mΩ ≦ ESR ≦ 300mΩ on the output ensures stability. Higher capacitance

values help to improve line and load transient response. The output capacitance may be increased to keep low undershoot and overshoot. Output

capacitor must be placed as close as possible to OUT and GND pins.

AP7366

Application Information (continued)

Adjustable Operation

The AP7366 provides output voltage from 0.8V to 5.0V through external resistor divider as shown below.

The output voltage is calculated by:

Where V_REF= 0.8V (the internal reference voltage)

Rearranging the equation will give the following that is used for adjusting the output to a particular voltage:

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 AP7366 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 V_ILand V_IH.

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

prevent over-current 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 250mA. Full current

is restored when the output voltage exceeds 15% of V_OUT. This feature protects the regulator from over-current and damage due to overheating.

Thermal Shutdown Protection

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.

AP7366

Application Information (continued)

Ultra Fast Start-up

After enabled, the AP7366 is able to provide full power in as little as tens 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.

Low Quiescent Current

The AP7366, consuming only around 60µA for all input range, provides great power saving in portable and low power applications.

Power Dissipation

The device power dissipation and proper sizing of the thermal plane that is connected to the thermal pad is critical to avoid thermal shutdown and

ensure reliable operation. Power dissipation of the device depends on input voltage and load conditions and can be calculated by:

The maximum power dissipation, handled by the device, depends on the maximum junction to ambient thermal resistance, maximum ambient

temperature, and maximum device junction temperature, which can be calculated by the equation in the following.
