AP7343

AP7343
300mA HIGH PSRR LOW NOISE LDO WITH ENABLE
Description
Pin Assignments
The AP7343 is a low dropout regulator with high output voltage
accuracy, low RDS(ON), high PSRR, low output noise and low
quiescent current. This regulator is based on a CMOS process.
EP
The AP7343 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 AP7343 is well suited for low power handheld communication
equipment.
PIN1 – VOUT, PIN2 – GND, PIN3 – EN, PIN4 – VIN
The AP7343 is packaged in X2-DFN1010-4 (Type B) and SOT25
packages, allows for smallest footprint and dense PCB layout.

Function
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

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 period 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
1oz. internal power and ground planes and 2oz. 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 VOUT pulled to GND.
8. This specification is guaranteed by design.
9. To make sure lowest environment noise minimizes the influence on noise measurement.
10. AP7343 has 2 options for output, built-in discharge and non-discharge.
11. Potential multiple grades based on following output voltage accuracy.

AP7343
Application Information
Output Capacitor
An output capacitor (COUT) is needed to improve transient response and maintain stability. The AP7343 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 AP7343 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 times. 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 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 V IN 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.
Measurement conditions: Frequency Band: 10Hz to 2MHz, Temperature: −40°C to +85°C.
