Description
Pin Assignments
The AP7361 is a 1A, adjustable and fixed output voltage, ultra-low
(Top View)
dropout linear regulator with enable. The device includes pass
element, error amplifier, band-gap reference, current limit and thermal

The characteristics of the low dropout voltage and low quiescent
current make it suitable for low to medium power applications, for
U-DFN3030-8
example, laptop computers, audio and video applications, and battery
powered devices. The typical quiescent current is approximately
( Top View )
70µA. Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions.

The AP7361 is available in U-DFN3030-8, SOT89-5, SOT223, TO252
and SO-8EP package.

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 AP7361 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.
Adjustable Operation
Adjustable operation is not available in the SOT223 TO252 and SO-8EP package.
The AP7361 provides output voltage from 0.8V to 5.0V through external resistor divider as shown below.

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:
⎛V
⎞
R1 = R2 ⎜⎜ OUT − 1⎟⎟
⎝ VREF

To maintain the stability of the internal reference voltage, R2 need to be kept smaller than 80kΩ.

Application Information
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 ON/OFF feature is not available in the SOT223 and TO252 package.
The AP7361 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
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 200mA. Full current is
restored when the output voltage exceeds 15% of Vout. 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.
Ultra Fast Start-up
After enabled, the AP7361 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 AP7361, consuming only around 70µA 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:
PD = (VIN - VOUT) X IOUT
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:
PD (max@ TA ) =
( +150°C - TA )
