AP7341

Description

The AP7341 is low dropout regulator with high output voltage
accuracy, low R

DSON

, high PSRR, low output noise and low quiescent

current. This regulator is based on a CMOS process.

The AP7341 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 AP7341 is well suited for low power handheld communication
equipment.

The AP7341 is packaged in an X2-DFN1010-4 package and allows
for smallest footprint and dense PCB layout.

Thermal Pad

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.

Note: 4. a). Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
device. These are stress ratings only and functional operation of the device at these conditions is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
b). Ratings apply to ambient temperature at 25°C . The JEDEC High-K board design used to derive this
data was a 2 inch x 2 inch multilayer board with 1-ounce internal power and ground planes and 2-ounce
copper traces on the top and bottom of the board.

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.

6. Quiescent current is defined here is the difference in current between the input and the output.

7. Short circuit current is measured with V

8. This specification is guaranteed by design.

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 AP7341 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
generally used to reduce trace impedance. Wide trace should be used for large current paths from VIN to 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
between I
Measurement conditions: Frequency Band : 10Hz to 2MHz, Temperature: −40°C to +85°C

(Output Current) and ESR of an output capacitor are shown below. The stable region is marked as the hatched area in the graph.
