AP7342

DUAL 150mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

Pin Assignments

The AP7342 is a dual 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.

Each regulator includes a voltage reference, error amplifier, current

limit circuit and an enable input to turn on/off output. With the

integrated resistor network, fixed output voltage versions can be

delivered.

With its low power consumption and line and load transient response,

the AP7342 is well suited for low power handheld communication

equipment.

The AP7342 is packaged in X2-DFN1212-6 package and allows for

smallest footprint and dense PCB layout.

Application Information

Output Capacitor

An output capacitor (C_OUT) is needed to improve transient response and maintain stability. The AP7342 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 GND 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 (C_IN). A minimum 0.47µF ceramic

capacitor is recommended between V_INand GND pin 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 V_INand GND pin.

Enable Control

The AP7342 is turned on by setting the EN pins high, and is turned off by pulling it low. If this feature is not used, the EN pins should be tied to V_IN

pin to keep the regulator output on at all time. To ensure proper operation, the signal source used to drive the EN pins 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_OUTpins are 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 GND pin 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 V_INto V_OUTand load circuit.
