AP7340  
150mA HIGH PSRR LOW NOISE LDO WITH ENABLE  
Description  
Pin Assignments  
The AP7340 is a low dropout regulator with high output voltage  
accuracy, low RDSON, high PSRR, low output noise and low quiescent  
current. This regulator is based on a CMOS process.  
The AP7340 includes a voltage reference, error amplifier, current limit  
circuit and an enable input to turn it on and off. With the integrated  
resistor network, fixed output voltage versions can be delivered.  
With its low power consumption and line and load transient response,  
the AP7340 is well suited for low power handheld communication  
equipment.  
The AP7340 is packaged in an X2-DFN1010-4 package and allows  
for smallest footprint and dense PCB layout.

In PCB layout, it is preferred to use large copper area to cover this pad for better thermal dissipation,  
then connect this area to GND or leave it open. However, do not use it as GND electrode function

AP7340  
Application Information  
Output Capacitor  
An output capacitor (COUT) is needed to improve transient response and maintain stability. The AP7340 is stable with very small ceramic output  
capacitors. The ESR (equivalent series resistance) and capacitance drives the selection. If the application has large load variations, it is  
recommended to utilize low-ESR bulk capacitors. It is recommended to place ceramic capacitors as close as possible to the load and the ground  
pin and care should be taken to reduce the impedance in the layout.  
Input Capacitor  
To prevent the input voltage from dropping during load steps it is recommended to utilize an input capacitor (CIN). A minimum 0.47μF ceramic  
capacitor is recommended between VIN and GND pins to decouple input power supply glitch. 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 VIN and GND pins.  
Enable Control  
The AP7340 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 VIN  
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.  
Short Circuit Protection  
When VOUT pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 60mA. This feature  
protects the regulator from overcurrent and damage due to overheating.  
Layout Considerations  
For good ground loop and stability, the input and output capacitors should be located close to the Vin, Vout, and Gnd pins of the device. The  
regulator Gnd pin should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. Ground plane is generally  
used to reduce trace impedance. Wide trace should be used for large current paths from VIN to VOUT, and load circuit.  
ESR vs. Output Current  
Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low ESR also can be used. The relations  
between IOUT (Output Current) and ESR of an output capacitor are shown below. The stable region is marked as the hatched area in the graph.

Frequency Band: 10Hz to 2MHz, Temperature: -40°C to +85°C
