The characteristics of low dropout voltage and low quiescent  
current make it suitable for low power applications, for  
example, battery powered devices. The typical quiescent  
current is approximately 65μA.

300mA, LOW QUIESCENT CURRENT, FAST TRANSIENT  
LOW DROPOUT LINEAR REGULATOR  
Application Note  
Input Capacitor  
ON/OFF Input Operation  
The AP7331 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  
A 1μF ceramic capacitor is recommended to connect  
between VIN 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 less noise. For PCB layout, a wide copper  
trace is required for both VIN and GND. A lower ESR  
capacitor allows the use of less capacitance, while higher  
ESR type requires more capacitance.  
Characteristics section under VIL and VIH.  
Current Limit Protection  
Output Capacitor  
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  
600mA to prevent over-current and to protect the  
regulator from damage due to overheating.  
The output capacitor is required to stabilize and help  
transient response for LDO. The AP7331 is stable with  
very small ceramic output capacitors. The recommended  
capacitance is from 1μF to 4.7μF, Equivalent Series  
Resistance (ESR) is from 10mΩ to 200mΩ, and  
temperature characteristic is X7R or X5R. Higher  
capacitance values help to improve load/line transient  
response. The output capacitance may be increased to  
keep low undershoot/overshoot. Place output capacitor as  
close as possible to OUT and GND pins, and keep the  
leads as short as possible.  
Short Circuit Protection  
When OUT pin is short-circuit to GND or OUT pin voltage  
is less than 200mV, short circuit protection will be  
triggered and clamp the output current to approximately  
100mA. This feature protects the regulator from over-  
current and damage due to overheating.  
Adjustable Operation  
The AP7331 provides output voltage from 0.8V to 5.0V  
through external resistor divider as shown below.  
Thermal Shutdown Protection  
Thermal protection disables the output when the junction  
temperature rises to approximately +140°C, allowing the  
device to cool down. When the junction temperature  
reduces to approximately +125°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 AP7331 is able to provide full power in  
as little as tens of microseconds, typically 80µs, 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.

Fast Transient Response  
Fast transient response LDOs can extend battery life.  
TDMA-based cell phone protocols such as Global  
System for Mobile Communications (GSM) have a  
transmit/receive duty factor of only 12.5 percent, enabling  
power savings by putting much of the baseband circuitry  
into standby mode in between transmit cycles. In  
baseband circuits, the load often transitions virtually  
instantaneously from 100µA to 100mA. To meet this load  
requirement, the LDO must react very quickly without a  
large voltage drop or overshoot — a requirement that  
cannot be met with conventional, general-purpose LDOs.

To maintain the stability of the internal reference voltage,  
R2 need to be kept smaller than 125kΩ.  
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.

Application Note (Continued)  
Fast Transient Response (Continued)  
Low Quiescent Current  
The AP7331’s fast transient response from 0 to 300mA  
provides stable voltage supply for fast DSP and GSM  
chipset with fast changing load.  
The AP7331, consuming only around 65µA for all input  
range and output loading, provides great power saving in  
portable and low power applications.  
Small Overshoot and Undershoot  
Wide Output Range  
The AP7331 has small and controlled overshoot and  
undershoot in load and line transitions. This helps to  
protect supplied circuit from damage and operation error  
caused by glitches. This feature also permits the usage  
of small value output decoupling capacitor with AP7331.  
The AP7331, with a wide output range of 0.8V to 5.0V,  
provides a versatile LDO solution for many portable  
applications.
