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 RDSON, high PSRR, low output noise and low quiescent current. This regulator is based on a CMOS process. 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. The AP7343 is packaged in an X2-DFN1010-4 package and allows for smallest footprint and dense PCB layout.

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.
