P7340
150mA HIGH PSRR LOW NOISE LDO WITH ENABLE
Description
The AP7340 is low dropout regulator with high output voltage
accuracy, low R
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 a X2-DFN1010-4 package and allows for
smallest footprint and dense PCB layout.

Function
Enable pin. This pin should be driven either high or low and must not be floating. Driving this pin high
enables the regulator, while pulling it low puts the regulator into shutdown mode
In PCB layout, prefer 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 alone.

Application Information
Output Capacitor
An output capacitor (C
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.
) is needed to improve transient response and maintain stability. The AP7340 is stable with very small ceramic output
OUT
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 V
possible to the device to assure input stability and reduce noise. For PCB layout, a wide copper trace is required for both V
and GND pins to decouple input power supply glitch. This input capacitor must be located as close as
IN
and GND pins.
IN
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 V
protects the regulator from over-current and damage due to overheating.
pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 60mA. This feature
OUT
Layout Considerations
For good ground loop and stability, the input and output capacitors should be located close to the input, output, and ground pins of the device. The
regulator ground pin should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. Ground plane is
to V
generally used to reduce trace impedance. Wide trace should be used for large current paths from V

, 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
